Question
Ineed help with my 94 nissan d21 pick up.it hits rev limiter at 2,500 and its suppost to be at 6 how do I fix this problem

Answer
Bobby,

I do not know if you have a RPM limit problem or not.  It could be some other cause if you have not verified that the coil power is being cut by the computer (ECM).  I would check, with a digital volt/ohm meter to see if the power to the coil is actually being cut by the ECM.  If this is the case it is a programming issue and that would be an issue with the ECM.  Other causes would be a defective air meter cutting off signal or even a plugged converter preventing a higher RPM.
