ok well ive got a n 98 civic dx hatch that i swapped an obd-1 gsr into. i used the harness that came with the car which had an obd-1 b16 in before i bought it. (bought it as a shell). the harness was junk and had alot of unnecessary plugs and threw a code for air intake temp (CODE 10) so i bought a new one and converted it to obd-1. including the distributor wire. which was dumb. we plugged it in and it was mis-firing in clylinder #3. its getting spark and its getting fuel(my oil pan is full of it). i changed the spark plug and the spark plug wire. nothing changed. so i converted it back to obd-2a and bought the jdm distributor jumper. and its still mis-firing. and suggestions? and its been throwing code 10 on both harness's. bad sensor?... and ive had a cracked dizzy cap on it since baught the motor. no mis-fire on the first harness. only on the second harness

 

bbbbuuummmmpppp

 

 

did you ever purchase a new dizzy cap? did you test the ignition control module?
