92 318is no power at 3000 rpms !! PLEASE HELP
PLEASE HELP MEE !!!
I have a 1992 318is
The car will start and idle with no problem, purrs like a kitten all day, sounds great, no knocking or erratic idle. As soon as you hit the gas to rev it up around 3-4000 rpms, it bogs down, spits, sputters and sounds like it gonna stall. Let off the gas and it will go back to idle and run perfect again.
also i can drive the car when its cold FINE, no problems, only once its warmed up does it start
Ive changed plugs, coils, checked the cat, installed 2 different DME computers, valve cover gasket, coolant temp sensor, idle control valve,
fuel filer, vaccum lines... EVERYTHING !!
Anybody have any suggestions or ever heard of this ?
Its weird to me that its fine and runs great when cold, and even at idle and between 0-2500 rpms, only above that when its warm does it do this !
anything would be appreciated thanks !
