Vehicle: 92 CX hatch
Engine: 97 B18C1 converted to OBD1
Problem: The car originally had a VictorX manifold which I was looking to swap out for a stock GSR manifold. I mistakenly purchased a 1999 OBD2 intake manifold but I thought I worked out everything correctly (I'll have pics up tomorrow).

The car had been running great up until this point so I'm guessing I just messed something up somewhere with a vacuum line.

There were four CEL's when I read them earlier, 3 - 10 - 14 - 21 if I remember correctly. The car starts and only stays running if I lay into the throttle and keep it over 1500rpm, it sounds good while it's running but the minute I release the throttle it falls flat on it's face, revs once or twice as if it had some large cams, then dies out. P06 ECU, wired for knock sensor, not wired for IAB's so I tried capping it off. I used the FITV and IACV from the OBD2 manifold, is there a difference between the OBD1 units that I had on before wtih the VictorX manifold?

3 - Map Sensor
10 - IAT - intake air temperature sensor
14 - IAC (EACV) - idle air control valve
21 - VTEC spool solenoid valve

EDIT: 3 and 14 went away, still idles very poorly and won't idle unless I give it some throttle

Thanks

bump

 

my guess is that u have the IAT and the IACV plugs mixed around sounds like the IACV is plugged it if u having to give it gas for it to stay running try switchin them two plugs around or what happen to me was that i didnt extend the wires for the iacv and the motor moves so much it pulled the wires out of the plug and wasnt getting a connection to the iac and had same problem as you did. Theres no difference in those units OBD1 or II doesn't matter.

 

Looking back, I thought the IAT wire was a little short when putting it back on - that'll be the first thing I check in the morning.

 

double check all your wires.. take off the plugs try then somewhere else.. reset battery.. and turn to acc and check for cel again.. if its still on, read it and redo.. this is how i always check mines...

 

Sorry for the late update, the harness for my Apexi VAFC2 became unplugged under the carpet. I plugged it in and the car runs perfect again
