325is high rpm power loss
Hey there. Ive already got a ton of experience with my M42 and ive been looking at a 325is that is reeally cheap and of course its got a problem. But anyways ive been kinda trying to figure out what the problem is before i decide to pull the trigger on this one.
Whats happening is that in the lower rpm's, it runs just fine. But once you really give it the beans, it will start to kinda hesitate and sputter once it gets over 4000 rpm. Now im guessing that is has something to do with the fuel system. I was thinking maybe the fuel pressure regulator or a dirty filter? i mean any ideas would help right now. Because i have been wrong in the past. So go ahead and chime in! give me your ideas!!
