2000 xj loss of power

[Burton58]

while driving, get to a light or stop sign and start to go again the jeep will stumble over itself, revving up and down but not going faster with throttle input. give it a few and it's fine again. no CEL. TPS? other sensor issue? drives perfect otherwise, very intermittent

[Burton58]

Bueller?

[Burton58]

you guys are no help

It may sound crazy, but I've had bad gas before. Completely fucked everything, added a cleaner, get the water out, drove a bit and full up with the best octane I could and the problem resolved. This was a few years back in pa, but a simple easy trial.

[Burton58]

hmmm idk if water would stay in there. it's been doing this awhile and been through 20+ tanks of gas

[Hudson]

Just when dropping from load to idle? Does it die?

[Burton58]

it's during acceleration. doesn't want to go for a minute then is fine. idle is fine

Part out

[Ruepart Hoaxley]

Could be TPS but doubtful, it'd be more obvious I'd think.

Try just cleaning the throttle body? Check the plug gap? Fuel rail pressure? If the rail pressure is too low or the injectors are clogged, they can still put out enough gas to idle fine, but once a load is put on them they starve out.

Is this just during warm up or at anytime.?

[Burton58]

Anytime. I've been driving it for 3 days now and it did it to me once on the way home from work. Shifted to neutral, revved it a bunch and its fine. Very intermittent

[hoggie101]

i had to drive mine tonight like an imaginary stick it sucked but i think its because i have no back pressure

[Burton58]

Apparently this thing stalled out the other day. Otherwise it's been fine

[crosbike]

try cleaning the throttle body and IAC valve. worst thing to come of this is a clean throttle body and IAC. Reason i say IAC is my gf's jeep seems to stutter when i get on the throttle right after i start it, every start. But its fine after that. I dont know but it may be an issue with the IAC closing and throttle blades opening. Just a thought

[CSaddict]

Mine did this forever. Turns out it was the chinese CPS I put in it. Took months to figure it out. Swapped damn near everything out and had it on the scanner datalogging it 4 times. On a chance I installed one I had kicking around and fixed it. Been great ever since.
