Hi, i have had this problem for quite some time and recently its getting worse. Whenever i rev the car(moving) or some spirited driving, sometimes after high reving, the car just misfires, the car is like undergoing fuel starvation and if i want the car to accelerate, i have to floor the pedal till the end, then only the car will go. Its so obvious when im driving up a slope. If there's misfire, i have to off and on the engine again. After restarting the engine, its fine again. When the problem occurs, if i put the car in neutral, the car rev will be damn low and eventually dies off.

I have changed the following item. brand new ICV, brand new fuel filter, brand new crankshaft sensor(pulse generator), brand new blue temp switch sensor. The problem is still there. Please take note that the problem is really obvious if im driving uphill or a slope.

The problem occurs even my fuel tank is full. Im suspecting fuel pump, anyone?
Help, im so lost now.
Thx

Chris

bro... as what i mentioned before have you check plug cables yet? i think it is nothing to do with fuel management. Its electrical. Please, get half cut shop rotor arm and a good set of plug cable.

ok bro, will take your advice. Thx

BTw, im using 083 AFM on my E30 325i...its suppose to be 028 AFM. Isn't it weird?

mmm???? why lor? anyway, if you have a good relation with half cut shop, normally they will let you test first for your R&D. Provided you have to pay first. Gud Luck!
