I have a 1993 manual 318i that goes well but loses all power after 5k RPM, it seems like the fuel pump is cut, almost like it has redlined but I the techo says redline is at 6.5k, what could be causing this!

Any idea what motor! It could be a few things but there were some issues with calibration of the flap style airflow meters. If you post up your number plate of last 7 digits of your VIN we can find your engine details.

Check for a leaky or cracked intake pipe between the AFM and the throttle.

Some engines lower the red line when the engine is cold, or THINKS its cold, maybe coolant sensor!

That could be it as lately the temp guage has been all over the place.
