I saw the high idle in your other logs as well. Pretty sure it's not the bin, it's the same thing that drove me nuts on a vehicle, even after testing IAC and IAC wiring it still was happening. Replaced the IAC and it went away... month later same thing, different truck, replaced IAC and it went away. This time I tore apart the IAC to find it stripped in middle... Hope that's your issue.

There's a smooth tool in TunerPro, takes a little practice but works well, way easier to dial in issues and fuel VE tables when smooth.

You can get a lope with TBI at idle, have to run Open Loop Idle, then some playing with Idle RPM, fuel, spark idle bias etc... rev engine to dry out wet intake, test drive and see how it does when come to idle again. Have to keep the RPM up for cold starts, if you don't get it right it will load up after a couple minutes. Really a lot of work to make an EFI system run wrong and still run right off idle...
