hey all, i have posted on this a few weeks back, but I have still not found out the problem.
When I am accelerating, the engine seems to cough and sputter, particularly if i am putting a little bit of gas into it. It also seems to happen a bit more often if the engine is warm. It can happen in any gear, (98 tj 5 spd 4 cyl), but seems to happen a bunch in second... i'm thinking i may just naturally accelerate a bit harder when in second.
additionally, when i start up i find the tj idling around 500 rpm, which is lower than anything else i have driven. also, if i am backing out of a parking space, doing a three point turn, or braking suddenly, especially if the jeep has just been started, the engine actually dies.
I have replaced the tps, ran seafoam through the air intake and through the gas tank, changed the oil, changed the plugs, cap, wires...
does anybody have a clue.... ever experienced this problem before.
thanks in advance,
