i have bought a E30 318lux 1991.

when it gets to around 55000rpm / 6000rpm it misses and splutters. where is the limiter set on these?

i have changed plugs and leads. one of the leads has to be pushed through a pickup ring? what is that as that has a crack init, Would that cause my problem?


Thanks lee

A worn cam can give an effect exactly like a rev limiter in the M40 engine.

any idea what that pick up is that the lead goes through

Sensor around the lead is the equivalent of a cam position sensor. The engine will run perfectly OK without it, throughout the whole rev range, but will run slightly better with it.
