In this video we have a look at a 2010 Chevrolet Malibu LS 2.4L, L4, Flex, VIN 0, Des LE9, 16V, DOHC. The customer complaint was poor running when cold, skips, chuggles, coughs and stalls but only when cold. We get a good reminder that not all problems are fixed with wrench's and screwdrivers. We show how to reset the alcohol content value back to zero and preform the flash programming update to correct the issue. P0171, P0172, P1174, P0131. -Enjoy!

    Flex fuel Toyotas have the same issue with forgetting the alcohol percentage and starting like crap.

    I live in Florida and even when its warm my car knocks/taps on startup. And lately has started to stall.

  6. Avataaar/Circle Created with python_avatars Andy Citarella says:

    Cars went from needing a mechanic to needing a mechanic & a IT Tech. How is a DIY supposed to do this? Most of us don't own a Bi-Directional scan tool that can do programming. Sad the way the industry has gone.

  7. Avataaar/Circle Created with python_avatars The OG Kingler says:

    I have a 03 and just replaced the air control sensor it still stalls only when I come to stops idk what to do anymore mines not flex it’s the old 3100

    The mechanical world was turning that way back when I was a young shade tree mechanic and it's been getting progressively worse by the day ever since

    Wow I thought there would be updates. Mine is a 2015. Do you think it takes updates? Also I'm in Indiana and I may come to you cause I got an issue I cannot figure out

  12. Avataaar/Circle Created with python_avatars John Doe says:

    Once again thanks for the video 🙂
    Quite interesting that it's different enough to run pooh with high alcohol fuel on old firmware…
    Java? Java is involved in reflashing a PCM?
    Ewwwwww! Icky! Hahaha!

    Mine was a cracked exhaust manifold. Always check under the heat shield.

  15. Avataaar/Circle Created with python_avatars Omar David Gonzalez says:

    Question could that apply to a non flex fuel malibu because my car got a code p2097 rich fuel problem

  16. Avataaar/Circle Created with python_avatars Joshua Marshall says:

    It would aggravate me to death to work on somebody's car that can't even keep the inside clean. If the inside looks like that, you know it didn't get the maintenance it should have

    You need to be a computer nerd to work on today's cars. Eric your knowledge amazes me.

    Hi Eric. Hey, you don't know why they put a counter in the computer programs when they are never really accurate? For the same damn reason you can buy vehicles with technology that could get you to the moon, but they still put gauges in the dash that may be accurate at one mark, but are marked so strangely that it would take a mathematician to figure out the spacing between the hash marks on the rest of the stupid gauge. You look at the alternator gauge in most any vehicle with an alternator gauge and I challenge you to find one that resembles a normal gauge marked in regular spaced increments like 1, 2, 3, 4, or 5. Not .7 or 1.2 or 2.6 or 4.9 like my alternator gauge. That drives me berserk! You do the math and tell me the voltage it's reading! I quit. I'll take an idiot light over gauges like that any day. They can keep em! Jpol.

    Hey Eric just stumbled across one of these same engine same year down in North Carolina with the same problem. There is also a P0420 in memory. I have a generic obd reader so can't do the reset how much do you think Chevy may charge for the reset and update? I also explained to the customer that they have a CA Emissions Vehicle and that the Cat will not be cheap.

    Scary mr o,I can think of a shop not far from me ,has all the latest tec, cars go in running ,never leave runners,he charges mega,even when it’s now a none runner,what you just did I have stayed away from because of the shop,but I can see that was wrong,get video mr o.

    She thought it needed a tune up or something. So she dumped in 3 cans of dry gas and the computer recognized it had a lot of alcohol and compensated for it.

  24. Avataaar/Circle Created with python_avatars Jordy de reus says:

    Alcohol in your drink. Fuel in the Tank. Not the other wat around…..

    Don't computer programmers have a saying, "garbage in, garbage out", or something to that effect..:-)

  26. Avataaar/Circle Created with python_avatars Mike Chiodetti says:

    Great Video! Definitely saving this one! I'm surprised the commies up in Sacramento never sanctioned E85 for my area!
    The L.A. DWP actually put that trash in small auxiliary engines. Every day you have to run it, and drain it out when it gets cold, or…..LOTS of parts cleaning when the stuff gels, separates,…..etc!

  27. Avataaar/Circle Created with python_avatars Doubledge007 says:

    Usually when my computer is running slow I just unplug the battery for 10 seconds and plug it back in….works great.

  28. Avataaar/Circle Created with python_avatars Ellesmere Wildwood says:

    What I find frightening is not the ever increasing complexity of our vehicles but rather the ever diminishing amount of highly skilled techs to find problems. Dealerships won't pay top technicians the top money so they branch out to work on their own. Which is fine but that leaves us consumers not knowing where the top technicians like Eric can be found and sadly, more often than not, we fall victim to those far less able.
    I found your channel about a month ago and I've been binging to catch up. I'm in Melbourne Australia and my experiences over the years with mechanics and so called technicians have not been very happy ones. I drive a 2005 Mitsubishi 380 3.8 v6 that's had a niggling electrical issue since I bought it almost new 13 years ago. It isn't serious, keeps pulling up "soft codes", I've been managing it but no one has had the gumption to find the problem.
    I gave up on Mitsubishi and then paying "techs" to find the problem who never could despite paying for diagnostics. If I was in the U.S. I'd bring it to you in a heartbeat. Good on ya Eric, I've been enjoying binging on your videos, your style and attitude to your repairs and life in general.

    I am about to start a college course in Agricultural Engineering this September, tractor technology is apparently only now starting to embrace CAN bus and electronic control modules. The course tutor told a story about how when a farmer called in a fault on his new tractor and a lad turned up with a laptop to fix it, he refused to pay the bill, because he thought he didn't fix it and the young guy was just playing with the laptop on his time! As a former IT guy, I am interested by your videos of doing diags with scantools, etc. but generally I like the rewarding nature of fixing stuff with your hands, which is sadly quite far removed from working on computers these days, very few IT techs work on hardware, it's all software stuff that your boss wants you to fix as fast as possible over the phone or via remote access… Thanks Eric!

  30. Avataaar/Circle Created with python_avatars Aaron Johnson says:

    A GM tech 2 huh??? kind of an elitist scan tool. your snapon scanner looks better on camera.

    U dam good man like watching ur video s keep it coming Sir thanks

  32. Avataaar/Circle Created with python_avatars Ynnel?! says:

    just put a block heater on it!

  33. Avataaar/Circle Created with python_avatars Lewis Biggs says:

    Now I've loved your videos for a long time, I'm a nerd and love seeing the way you find problems. But goddamn I hate this car computer business, used to be you'd need a screwdriver to fix a fuel issue, or just bash the carb with something heavy till you could fix it!

  34. Avataaar/Circle Created with python_avatars J D says:

    My dad had over 34 years in auto repair. He owned his repair shop. He did not want to adapt and retired. My expertise is in electronics and computers. He used to call me out to the shop to help diagnose electronic problems. I thought the newer cars were much easier to work on than the older ones. LOL

  35. Avataaar/Circle Created with python_avatars Salvatore III says:

    What made you think it was a updating issue? Sorry if I sound dumb

  36. Avataaar/Circle Created with python_avatars dm7097 says:

    Is there an update for that filthy interior? S.m.h.

  37. Avataaar/Circle Created with python_avatars fredrick harper says:

    You're right about doing a tuneup on the new vehicles. your thoughts on a 05 dodge caravan 3.3 non flex fuel, no service engine light but acts like it's not getting enough fuel especialy
    when not up to operation temp, 105,000 mile on speedometer, I live in Pensacola, Florida

  38. Avataaar/Circle Created with python_avatars richard novak says:

    So true that I still driving trucks that are more dependable the new stuff

  39. Avataaar/Circle Created with python_avatars TheSpyder9876 says:

    I don't usually go for the diagnostic (ie fancy scan tool) videos simply because as a DIY I get confused with all the tech in these cars. However I think this was the most entertaining SMA video I've seen. Thanks Eric, I learned a lot just now.

  40. Avataaar/Circle Created with python_avatars Shawn Montgomery says:

    Any chance you could do a quick video explaining fuel trims? If you have one already I'd like to find it. Thanks.

  41. Avataaar/Circle Created with python_avatars jw '46 says:

    Looks like there might be a good reason for the 'recall' notice on my new Chevy pickup. It arrived in the mail a week after I brought the truck home, and I copped an attitude.

  42. Avataaar/Circle Created with python_avatars BLACKANDYELLOWGARAGE says:

    Around my neck of the woods I am given the title of Superman for solving automotive problems. I relinquish this title to you Eric. Remember if you can do it I can too. This video was great.

  43. Avataaar/Circle Created with python_avatars zoidberg444 says:

    Nice one Eric. Very interesting to see some programming.

  44. Avataaar/Circle Created with python_avatars BChrisL says:

    I think the digital systems are far superior to the old mechanical control systems.

    Anyone who lived through the "lean burn" days of the first attempts at "smog control" might, if they can remember what day it is, tell you of the engines that routinely stumbled as stalled as they warmed. Calibrated orifices that slowly advanced timing assuming the engine warmed at a specific rate. Huge catalytic converters that routinely got so hot that safety bulletins were issued warning people not to park over dry grass or leaves due to fire hazard.
    Things are better and different. Before the service, that car was running poorly, after the service it was running much better.
    Points and condenser just don't cut it anymore.

  45. Avataaar/Circle Created with python_avatars rrcoster says:

    When technology came popular everything expedite and now you see it in just about everything from vehicles, refrigerator, washer and dryers, all electronics. Kudo Eric O on another successful repair and yes either have to adapt to new technology in everything or your kind screwed with trying to diagnose or repair anything new
