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 an 99 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. 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

One thing I know is on OBD2a there is no FITV. Is the engine surging when you let go of the gas(may be hard to tell if it dies almost immediately)?

 

Lol i have the same problem on my 97 gsr except its only 3, 10, and 14. I cleaned my map sensor and now the CEL 3 isnt comming on anymore but I just bought a new IAT and I will get it 2morrow to see if it'll work. Still no hope for my IAC since its not working at all. I dont know if its the wires or the actually IAC because I've tried 2 working obd1 IAC on my skunk2 manifold and it still doesnt work. Does any1 know if obd1 IAC works with OBD2 cars?

Sorry, manifold was from a 99 not a 97 that was a typo

Ha my #3 and 10 went away but my IAC is still no good I also have to give it throttle until its warmed up in order for it to stay alive.

 

Going to work on it a little more tomorrow, and try to get pics again - I forgot my camera last time

 

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
