hey,
I have a 93 r32 skyline and ever since i have bought the car about a month ago when i am sitting at idol the Revs fluctuate up and down around 100 -300 revs, also misfires occasionally
i have only really noticed this when its just sitting and idol and will get worse if i leave the car to idol for long periods
it does not do this when the engine is cold and the choke is on, it really only happens when the car is warm/hot
i have recently replaced the air flow meter, oxygen sensor and had the TPS (Throttle position sensor) adjusted
If anyone knows of wat could be making my car do this or have any suggestions don't hesitate to Post
cheers
