    Erik did you make video on that 67 on lift ? I built 66 drag car.

  2. Avataaar/Circle Created with python_avatars Got2getit20 says:

    My 14 Malibu makes a rattle noise only cold starts and soon as I cut it off and turn it back on it doesn鈥檛 do it but when it sit for 15 minutes it will do it!

  3. Avataaar/Circle Created with python_avatars Daniel Weithers says:

    We did this to the same car and now the idle is at 3000 rpm until we put it in drive

  4. Avataaar/Circle Created with python_avatars Luis Hall says:

    got gas, parked the car in some gravel, started it up and got this code.

    an 09 cobalt base xfe model, opened the lower pump seemed fine. then opened that rear pump valve and lots of carbon. did some diesel injection. on first start up i can hear one of the pumps.

    does the diaphram rip? or does it just get stuck open and wedges itself from moving? also there is a button on the unit, i dont know what it does or if its just a one way valve. can you cut the old unit in half?

    symptoms are choppy drive at steady throttle

  5. Avataaar/Circle Created with python_avatars 1111 says:

    besides the code, what were the symptoms?

  6. Avataaar/Circle Created with python_avatars SubLyriKal Productions says:

    My secondary air injector itself is bad, i cant find where its located anywhere online! Such a pain. If you have time could you please explain where it is so i can replace it? Would be greatly appreciated. Thanks!

    Thank. You Eric. I own 2012 Chevy Malibu with 2.4 liter. I learn more about my engine.

    What scan tool do you recommend?

  12. Avataaar/Circle Created with python_avatars tallswats22 says:

    Which do you like better the Autel in the vid or the new Bosch scanner? I know the recording sucks on Autel live data

  13. Avataaar/Circle Created with python_avatars Tony La says:

    Thanks

  14. Avataaar/Circle Created with python_avatars Jon Salzman says:

    @southmainauto is there any consideration when removing the hose that runs to that valve? Unfortunately GM designed it in such a way that it blocks one of the thermostat bolts, which is coincidentally what I need to replace!

  15. Avataaar/Circle Created with python_avatars Jessica D. says:

    Please help … my Malibu 09 … has no check light on .. rpms rev up when slowing down or letting off gas , my motor will rev up to t times ? Seems to be making my trans not shift well .. what could it be ? ANY HELP WILL GREATLY BE APPRECIATED

  16. Avataaar/Circle Created with python_avatars Richie G says:

    I have a 2010 Malibu with the 2.4L, I have a this brief noise on cold starts. After research I've learned that it is an air pump (I'm assuming it's the聽AIS)聽that is required for emissions in some states. In your opinion does this sound accurate to you and if so is there a way to quiet it down? Thank you in advance.

  17. Avataaar/Circle Created with python_avatars S L N says:

    Thanks for the video & Info….God Bless You聽 隆隆隆隆隆

  18. Avataaar/Circle Created with python_avatars John Reid says:

    Eric, is your Actron CP9670 capable of doing these test's? I am considering purchasing the Actron for home and you haven't done a review of it yet.

  19. Avataaar/Circle Created with python_avatars Cornelius West says:

    I just had this problem on my 10 Impala are these really that common on Chevy's

  20. Avataaar/Circle Created with python_avatars true2myself78 says:

    I have a 2011 Malibu my car will not accelerate when in drive or reverse. I cut the vehicle off then restart tge vehicle the car will then drive about 5 mins then accelerate slow down. What may this be???

  21. Avataaar/Circle Created with python_avatars Moggie20170000 says:

    I was working on a chevy truck with the same system. The intake fresh air hose was in a location that every time you drove thru a puddle of water it would suck water in. So I moved to to a higher location.

  22. Avataaar/Circle Created with python_avatars Moggie20170000 says:

    Do those east coast wiper blades come with paper attached or is that extra?

  23. Avataaar/Circle Created with python_avatars michael anderson says:

    good video nice 67 chevelle on the lift in the next bay

  24. Avataaar/Circle Created with python_avatars Charles Miller says:

    Is there a kit to update your car to have autopilot, you know so I can watch SMA videos while riding down the road.

  25. Avataaar/Circle Created with python_avatars 69chargerforever says:

  27. Avataaar/Circle Created with python_avatars Bottom Snagging Outdoor Adventures says:

    That sure is a fancy scope on a rope youre using there LOL I like it Thanks for all your awesome videos

  28. Avataaar/Circle Created with python_avatars Luigi Torchia says:

    How do you like your new test light? Is that a Mac Tool test light?

  29. Avataaar/Circle Created with python_avatars James Burgess says:

    Wonder if the owner of that pretty blue 67 would have an interest in a 400 small block. Its a 1980 2 bolt main short block with a crower perf cam, new chain, water pump, balancer & pulleys. Also have 882 bare heads, non EGR cast 4bbl manifolds, Rochester Quadrajet carbs. Not to far away in PA so would even deliver.

  30. Avataaar/Circle Created with python_avatars Pedro Galeano says:

    Cool video

  31. Avataaar/Circle Created with python_avatars BChrisL says:

    I'm with Mr Carroll, I thought air injection had gone the way of the carburetor and the metal oil can.

  32. Avataaar/Circle Created with python_avatars wyattoneable says:

    I like it.

  33. Avataaar/Circle Created with python_avatars RomanAutomotive says:

    Eric O, how you doing? Good I hope.

  34. Avataaar/Circle Created with python_avatars The Car Doctor says:

    Eric, how do you keep your hands so soft and supple? Any product that you recommend for keeping them from looking like "mans hands"? Oh, by the way. Nice video as always mate!

  35. Avataaar/Circle Created with python_avatars Richard Gill says:

    nice Dr o

  36. Avataaar/Circle Created with python_avatars twoeagle86 says:

    I got the same car, with that famous code po2135. we already changed the pedal and throttle body and it still goes into engine power reduce mode. dealer already changed the ecm, figuring that was that but still its doing that. What do you think it might be?

  37. Avataaar/Circle Created with python_avatars Mike鈥檚 Mechanic & Auto Body says:

    what kind of test light is that and where can i find one?

  38. Avataaar/Circle Created with python_avatars Serafin Silva says:

    I miss the good ol days when you only needed air/spark/fuel.

  39. Avataaar/Circle Created with python_avatars macboy19 says:

    Do the Subaru PZEO engines work in the same fashion? Are they worth the extra cost if something like this happens?

  40. Avataaar/Circle Created with python_avatars Jeffrey Battousai Strader says:

    Eric I'm waiting for the video where you get a Husqvarna riding mower and swap out the 24hp V-twin for a 395hp Hemi…..:-)

  41. Avataaar/Circle Created with python_avatars Smitty Smithsonite says:

    GM, payin' the bills, as usual! LOL

    That Chevelle in the background was close to GM's peak – all downhill from '73 on. 馃檨

  42. Avataaar/Circle Created with python_avatars atschirner says:

    Hey Dr O, what about a "Throwback Thursday" segment where you can dive in to lost technologies like points style ignitions? I bet you still have a flex shaft hex driver for setting dwell on GM's. Other topics could be drum brakes and generator charging systems with external regulators. Let's help the new kids, under 40, with old fart tech. Thanks again,

  43. Avataaar/Circle Created with python_avatars daveyio87 says:

    I'm glad my Malibu is an 08 and doesn't have that stupid system on it! I noticed in the video that Malibu had new variable timing solenoid valves

  44. Avataaar/Circle Created with python_avatars CARS LOVER says:

    the great blue Chevy please

  45. Avataaar/Circle Created with python_avatars Emt Scythe says:

    Awesome as always. You could also use a relay jumper like the Lisle set to turn the pump on. Yes these air pump systems are ridiculous. I deleted the one on my sons 93 F150. Yes it's a Ford but it was his Grandfathers truck ( mothers side, my dad would never drive a Ford lol ). I may have to pick up a digital test light just because.

  46. Avataaar/Circle Created with python_avatars Alan Tschirner says:

    Thanks for the straight poop on the bow tie. Can't wait for your next installment.

  47. Avataaar/Circle Created with python_avatars Hola! dkroth says:

    Ok, so you fixed this Malibu, what about that Malibu in the other bay?
