I am BUying a 1991 civic hatchback w/ a 90 crx si motor/tranny w/ dx intake manifold.

The only problem is that it seems to rev limit at 4000 rpm......

WHat do u think the problem is coming from?
\
Has anyone ever experienced this situation?

feedbacks please , if this problem is to complex to fix i'm not even gonna take it as a project car if its to big of a headache.

 

problem its caused by the crank angle sensor.
we were just dicussing it yesterday here
