I know Dave is going to swing by on Sunday to take a peek at it but I just figured somone here might be able to give me a few ideas.
Basically you start it and it runs rough. Like I vac leak.. a bad one. you give it gas above 2k and it seems better. If you drive it it'll move. Just when you let off the gas it feels like it's going to stall out. And it will if you let it.
The brakes are VERY soft. If you don't constantly pump them really quick it never builds up pedal. The brake light IS on. I did find something on some jeep forum that if you have no pedal and the brake light is on that the booster needs replaced. They said this would cause a rough idle too. Is it safe to say that if the brake booster is bad and is leaking, would cause a REALLY bad vac leak thus causing the car to run like ass at idle. Correct?
If that's the case, anyone have a 4.0L Jeep brake booster for cheap?
I've also read about taking some TB cleanerto the TB and such.
Then I also read about the CPS going bad.
I just don't want ot buy $200 in parts and it doesn't do shit. I know I have to eliminate things. We've already checked the timing, rotor, cap, plugs. I've changed the fuel injectors. We emptied the oil pan and it had a good 2 gallons of oil in the pan (yes.. most of it was oil/gas though maybe due to the old injectors being shit.
Alos, right before it shuts off at idle if I let it, the check engine light comes on and doens't come on when you turn it back on.
TIA.
