Re: Car wont run

I would double check all your connections to your coils for the spark plugs. Also, I'd go a step further and make sure all the spark plugs are torqued. If it wasn't running this rough beforehand, that's where I'd start. Also, make sure you post the codes when you've got them. That will help a lot in getting it all fixed.

Re: Car wont run

Here are the codes I keep getting
P0100 , p0400 ,p0048 . I swapped the plugs back over to the old ones and it's the same and gave me the same codes

Re: Car wont run

Did i miss something??? The jeep was running fine before the service and its not anymore after the service and now you regret that you bought it????
He, things can go wrong sometimes, but you can't blame the vehicle for that.
Check very well all the wiring at the places you worked and check for not properly inserted connectors and/or wiring which is pinched in between something.

Re: Car wont run

Jeep Grand Cherokee WJ - Diagnostic Trouble Codes

That's a link for every fault code for the WJ.

P0100 = Mass or Volume Air Flow Circuit
P0400 = Diesel EGR System Failure
P0048 = Doesn't exist?

Judging by those codes, I would say you may have lossened a connection by accident or forgt to plug something back in. Other than that, I'm at a loss for now.

Re: Car wont run

What country do you live in?

There is no service information on ANY of those dtc's, Chrysler doesnt use a mass air flow sensor, you clearly dont have a diesel.

So it starts and idles fine and just hesitates around 2500 rpm? Or does it run rough all the time at any rpm?

Re: Car wont run

I live in Australia

It starts fine but It if you let it idle after 5 mins is sounds like I gos to stall but starts to run again but if you put your foot on the gas as soon as you get to about 2500 rpm it hesataits really bad but when I pulled the plugs out there were some really white plug tips
