 · Once that was corrected and shielded, I had to reload the base file. I fought a fire but no start issue, until I reloaded again. Now it starts good cold or hot (IAC was set in the 3-10 range before the RPM Noise code showed up). But the issue now is a high idle with high IAC when it warms to temp.

LS Big Cam Idle

We'll define "stable" as +/- 50 RPM from the target idle speed you set. It's not easy to get a big cam to idle smoothly at 650 RPM (but it may be possible), so you want to go for something easy first. For example, if you have a cam that's between stock size and 224 degrees intake duration, try an initial target idle speed of 800 RPM.

 · The ECM is designed to idle at 950 +/- 50 and it isn't considered too high. Also, I would not consider adjusting the idle unless you have mounted a tach, which was the first add-on for my 900LT.
