since ive changed my filter i put a k&N filter and since then my car doesnt whant to rev higher then 4 500rpm
i think its the censor!!
i wouldnt mind telling me what u think?
I dunno..im not too familiar with BMW's. actually, Im not familiar with anything other VW CIS/lambda! Im guessing yer car uses a mas airflow sensor, its possible that you might've broken it when installing yer filter...but I really doubt it. Do you have any vacume lines going to yer airbox? Maybe you unplugged one by mistake when you were switching filters that can cause a f'ed up idle. I dont see why yer car wont rev over 4500 though, its weird. Are you trying to go past 4500 while driving, or when the car is parked. I was told that some cars have low rev limiters when there is no load on the engine.....
next time u come over to see my brother
or just come around here
come and try it
and tell me!
cause i dont wanna bring it to the garage and they start telling me i aftoo change all this @#%$!
