some background: 93 del sol Si (d16z6) with custom turbo kit. running Uberdata P28 with BBKA' map and 450cc injectors.. Upon finishing the install, the car starts up and runs fine for about 5-10 secs then it drops to 500rpm for a second or 2 and goes back up to 1500rpm and keeps doing this. It's throwing a code 14 (IACV). It didnt have this problem before the turbo install. Could faulty wiring on the resistor box cause this? Also we tried putting the AC on it stayed at a some-what smooth, constant 500-600rpm. Any help or input would be awesome. We also checked the vacuum lines we added and there appears to be no leaks.

Well, we switched IACV's with another car that has a good working one and it's still doing the same exact thing.
