hi i am new to the site and need a little help i have a e30 318i and for some reson it wont rev above 4500rpm i changed the fuel pump and it run fine for about ten min and then the fault came back again

Sounds like it might be a worn cam.
318's are renowned for this problem.
Whip the cover off & inspect the cam lobes closely. It'll be fairly obvious if it's shagged.

If the cams worn it will be caused by stiff hydraulic tappets and/or a worn oil pump.
So if you replace the cam, change the tappets as well.
To replace the oil pump is major work and just sa easy to get another engine because the main bearing will be next to go if the pump is shagged.

I had a similar problem to this on my old 316i.Changed the air flow meter and the problem dissapeared

thank you for all the info

i was thinking air flow because the engine in the car is a 318i but when i had the car it had a 316i engine in it that was no good so i changed the engine
