1JZ idle problems

[GN_Convert]

I have an AEM series 2 ECU, stock injectors, stock twins, AFPR and 3" exhaust. It runs good, but constantly oscillates at idle between 800-1400 RPMs. I am using an AEM wideband as the O2 source also. Reading other posts, I suspect it might be an IACV problem, but can I just remove it and block off the opening? I have tried shutting off the IACV output and it did not seem to make a difference.

Ideas?

Search youtube for "how to tune idle, series 2 aem". Its about a 15 min video on how to dial in the idle. It may give you some ideas.

Cause they all suck at the tuning.. My MKIII 1JZ with PTE1000, HKS 272's Idles fine.. no issues, I can actually start the car in real cold weather & the car starts right up.. It's all in the TUNING..
