I have a 325is that had a fuel pump issue back in may, so it sat while I picked up my eta sedan and drove that. I'm trying to get this a daily driver, I put a walbro 255 in it.
Its really hard to describe, but feels like the whole engine and driv etrain is shuddering up and down. Lack of power from idle to about 4k and anything above it cleans out and seems fine. The car has the bav auto chip.
It doesn't seem like a typical missfire from my experiences (of all times it was ignition failure) so I am wondering if the new pump is causing fuel starvation in the low end. The car basically has little power up to 4k rpm.
I read a bunch of missfire causes, but the car never drove like this before it sat. All injectors are clicking from what sounds the same pulse width but I will check if they do under a load at neutral. But even reving at neutral does not seem to affect how the tach operates.
Please pitch ideas, I need it as a reliable daily as my current sedan goes thru a major uphaul of body work. Thanks
