ive got a obd 1 zc in a 94 dx... the problem im having is that it wont rev over 3 grand. it hits the limiter and wont go any higher. iv changed out the dist. and the ecu.....still the same thing. if anyone has any suggestions or knows what the problem is it would be greatly appreciated.

 

make sure your air passage isnt blocked or clogged in some way...i had my cone filter on my intake go to far up the tube and it couldnt suck enough air so it wouldnt go above 2500...not saying thats it but its a similar experience...good luck

 

how does it idle?

 

i got it figured out... its the external crank angle sensor.... i need a obd1 gray plug zc dist. anyone have one?
