still working on my zc problem ran great for about a year then out of nowhere throw code 4. i have taken apart the dist. and cleaned it up cleaned up the other sensor thing on the end of the exaust cam too. still throws code 4 i gotta get this fixed please help. fyi it is in a 91 rt wagon, i traded it to a friend for his indy 500, so i gotta get it running for him.

 

new distributor, cleaning won't help. I believe 4 is the CYL/TDC crank sensor, that and 8. I couldn't find just the sensor except through Acura for over 100, reman dist, cap, rotor was 225.
