Good job!
Okay, I have been a mechanic for 0ver 30yrs.
I have watched some of your videos, and, would bring things to you for repair.
Anyone can plug a scanner in and see the codes, then start replacing parts to no end but, you double check your self and the tools you use.
Whenever I am going to replace an expensive part, I will check several different ways to make sure that is the bad part, so as to not be a parts changer.
Good job!
Your a great mechanic!
Nice and easy Repair Simple Diag On this one Just a bad Coil good work Eric O was very Entertaining @SouthMainAutoRepairLLC
I am on my 3Rd set of replacement coil packs, failing on 6 everytime after a relatively short amount of time. 130k total miles. The original lost 5 and 6. I am searching to see if it is caused by something else.
Hi, I have a 2002 Jeep Grand Cherokee, I installed a New 4.0 after the #6 piston came apart, drove it for a month, No codes. Now have codes PO300, PO302, PO304, this tells me cylinder 2, and 4 are misfiring. I replaced the plugs (gap 0.35) and a new coil. Drove it 2 days and the codes came back, but now it is cylinder 1 through 5 misfiring. It also has a o2 sensor code PO138 Circuit High and PO141 Heater Performance, both on sensor 1 bank 2. This is the only vehicle we have. Can you help?
My 2001 xj has always carried 50 psi but i use a mechanical gauge the original gauge says 10 psi i installed a brass tee at the oil sender you cant pay attention to the jeeps factory gauge it takes less than one hour to install a mechanical gauge
Thanks man
And that code 340 is that a cam position sensor
Hi I have an 01 Jeep Grand Cherokee with a 6 cylinder I have a code 340 spark plugs River chain supposedly the guy took a 2-2 get this thing running right change it but I really don't know is it a hard job to take the spark plugs out
i love the XJ
Soooooo much wrong in this video……
The most information in a nutshell…!!!! And Polish…. No joke..!!!!!!
Thanks for the video Mr. O! It's still helping people after several years. Polish engineering at its finest!
I just replaced the coil rail in my 04 grand cherokee 4.0 with 230,000 mi
I was getting a slight miss at idle that got worse over weeks and finally threw p0306. Plugs only had 6,000 miles on them but, number 6 had hairline cracks in the porcelain (which I think were caused by a bad coil). Replacing that plug made it better at idle but it still had a miss and was knocking when giving it gas while driving.
While I wasn't 100 % sure it was the coils, I replaced the coil rail along with new plugs and now it seems to be good
Damn it took me a second to figure out what the hell he was doing😂 I only have one coil and a distributor😂
I like the RIpp coil pack conversion kit for 2000- 01 Cherokee it’s a high performance kit that is awesome “ it’s around 300 bucks
I keep forgetting to give you the thumbs up but I remember this time
At least it’s not Chinese
I had that 'Six" in a Grand Cherokee (1996) with the 'low oil pressure'. Replaced the oil pressure sender and oil pressure was good as new.
The Jeep 4.0 is notorious for fouling the oil sensor … then people replace with cheap chinese one that fail even faster … buy the good OEM or OMIX ones … and or check with a good quality external gauge …. I've got over 550 K miles on 2 of these cherokees … that 4.0 is a solid engine … it also helps to upgrade to a 4 hole injector as they have the old chrysler 1 hole unit … bosch rebuilds are good (stay away from the cheap chinese ones) the bosch rebuild are 60 bucks, most have a lifetime warranty
Thanks Eric great job !! Is it possible the paired cylinder with the #6 coil is still operable and not creating a misfire for the paired cylinder. Was it possible to do a OHM coil reading on the #6 and compare with others for a confirmation ? Thanks again, great video !!
Thanks man! Great video! Appreciate you taking the time to share your knowledge
I got the same code on my 02 liberty and it has a tapping sound when idling and after it runs a few minutes start getting a little whitish smoke coming from the engine bay. What do you think that is?
There is a chance the O2 sensor problem was a result of the misfire, Good fix!

Those Jeep XJ 97 up oil pressure gauges are inaccurate sometimes & read low or drop off. I replace the sender no improvement. I found I had perfect oil pressure when I put a mechanical oil pressure gauge on my Jeep. About 15 lbs difference.
Awesome video, Great information… Thanks for the help.. God Bless you ❗✌❗💪❗

Love the video see this what I need a mechanic like you I trust u just watching this video I have blinking check engine gas smell going through my Exhaust I'm lost I smell gas on driver side not valve cover passenger side seems ok I haven't inspected anything I have to watch videos learn step at a time
You know Eric you are one of the smartest troubleshooters I have watched. Usually I can be way ahead of a lot of mechs. But proving you are Polish was loosing your license one day before you got it back, burning the tires off with Dad's car. When I was a teen I broke the pickup transmission doing very similar stunts and he made me put another transmission for punishment. Taught me a bit and probably easier for me than him in his 50's.
Didnt know they switched to those kind of coils all the ones I had all had plugs and wires and distributors
My '88 Jeep has one coil and a classic distributor.
My jeep due the same misfire 1999 jeep cherokee
have to say thanks, recieved the sma coffee cup, perfect to hold the java while checking out at your vids , thanks again
I have a 2015 Jeep cherokee, misfire on cylinder #2. My uncle replaced the Spark plugs and the coil and there's still a misfire on #2. What could be the problem sir?
