Hey guys im running a B16A1 with an AEM CAI, Skunk2 IM, Full MSD ignition, Fluidyne, Greddy oil catch can, and an Apex'i V-AFC. I am having a problem and I can't really figure out what is causing it.
First off, I noticed on my A/F ratio (Autometer) guage that the mixture was getting progressively richer. It could be simply that my guage is broken (but in that case wouldnt it just shut off). Anyways, now my car wont rev past 7000rpms in any gear. When i try to bring it past 7k the throttle completely cuts out. I checked and changed my oil to see if that would do anything and it didnt. I had no CEL and I looked at my ECU and it wasn't putting out any trouble codes. When I detached my V-AFC opnly then did he CEL come on and the ECU put out trouble codes, whihc could mean the V-AFC might be part of the problem? The ECU put out the trouble codes 22 and 23. I am not exactly sure which codes these are but I think code 22 is Vtec oil pressure switch. I brought it to a mechanic and he suggested the whole V tec soleniod had gone bad.

Someone has told me that my MSD SCI is the root of the problem, but i had that installed when the swap was done and the car ran perfect. If that is the case could someone please explain to me how an amplified ignition causes a Vtec malfunction

 

any input

need serious help....

 

well 22 is the oil pressure switch and 23 is the knock sensor. Try and check the plug on the oil pressure switch. as far as the knock sensor are you running one?
