Okay guys, I printed out the MPFI conversion from the FYI section (http://www.50mod.com/fourthgenhatch/mpfi.html) here on HT for my CRX DX and did the conversion per the diagrams. At the same time I dropped the B18a in and plugged all the harnesses in. When I started the car up, it was idling hard, and the ecu threw code 14, which is for the Air Idle Control Valve. The thing though, I took all the spare IAC on two other manifolds I have lying around and tried them, but that did not help. Baffled! I then went to the junkyard the other day and got myself 3 other IAC valves and to my confusion I got the same results. I'm not convence its the IAC valve that's the problen anymore. Idles reving at about 1.5k rpm. Please view all the instructions given on the link above. Were there any other wirings I needed to do?

Any suggestions would help a great deal!

 

help?

 

ok listen up.

1. disconnect ur battery for 20 min. (clear all codes)
2. get the cleanest iacv u got and put it on (make sure not to over/under torqe the bolts, and make sure sealing surfaces are clean)
3. check VERY well for vac leaks and replace any vac. line that looks bad
4. run car for ahwile at idle first and see if it throws a code, if not drive it stop and go (city driving) and see if it throws a code
5. post what happens.

 

Okay, so I forgot to mention, I did the whole process you have suggested. Disconnected the battery, checked for vac leaks (none), and I even cleaned the IAC's (all of them) per the instructions given on here using brake cleaners and air drying. Still does not solve the problem.

What else should I try out?

 

UP!
