Here's a good one guys this is on a 95 GC with the 4.0 and i just started to do this last night.


When driving the jeep you have to slowly give it gas after it gets past 3000 RPM or it starts to idle up and down making the jeep jerk back and forth matter.

But in nuetral you can rev it up all the way no problem. it run great untill you hit 3000 and idles no problem

Any thought?

 

Check the fuel pressure while under a load.

 

yeah im going to replace the little check valve on the fuel pump tomorrow and see what happens wish me luck

 

Okay if so if anyone has this problem it ended it up being a clogged fuel pump fuel filter

you have to take down the tank and take out the fuel pump and by the way you can't buy this filter they want you to buy the whole pump so you have to clean it and put it back.
