Z3 (1990) owner looking for some advice from some of you more experienced guys.
As suggested in the title, when I put my foot down to accelerate, the car pulls back completely and begins to decelerate. The only way I can describe this is as if it was building up the power, then it finally shoots off.
Not sure where to begin with this. Car revs fine and the actual accelerator is responsive. Going to whip out the spark plugs tomorrow and check them out.
Anyone got any ideas how to fix this/improve the acceleration? Seen on other places people have said to look at fuel system, but is there anyway to diagnose before I start messing around with everything - only a novice and it will take me time I don't have the luxury of!
