ok so my car is throwing a code 9 cyp code. i know its the cylinder position code. ive been searching threads trying to figure this out. i have a 2000 integra gsr with a b20 in it. im running a rywire step down harness to a obd1 ls ecu. ive tried diagnosing the problem, ive tried another distributor, ive tried another obd1 ecu, ive changed cap and rotor, i checked the dizzy for resistance everything i can not figure this out. also i read that when you have this code and your cruising at like 60 you sapose to bog, but i dont drives fine. but when your in like a low rpm youll feel a slight change in power like i have vtec or something. this code is always one as well. please help me i can not figure this out.

either incorrect jumper harness or bad ecu. Seeing that you have a 2000, OBD2B to OBD1/OBD2A jumper harness and if you have an extra ecu, try it. Are you wired for OBD1 or OBD2?

i have a obd2b jumper to obd1. ive tried my stocl obd1 ecu and i tried my stock p28. both throw the codes. i know the ecu are good cuz they were in my other car fine. and recently tried both in one of my friends cars. its all wired obd2. but i bought a obd2 gsr engine harness from one of my boys. idk if that could be the problem. but im going to try the diff jumper harness and see if that does the trick and was also going to try a obd2b ls ecu to see if thats changes anything.

you may have a bad wire somewhere. Get a multi, meter and start tracing the wire from the dizzy back to the ecu.
