So something strange has been ailing my cruiser for a few days now. When I go to warm it up in the morning, it high idles properly, but when it settles down into it's warm idle, it idles rough. Once you start driving, it runs fine. Once the truck is fully warmed up it idles almost perfectly with a barely perceptible miss at idle.
I feel like there's a slight hesitation under load, but again, it's barely perceptible.
Background info:
-new plugs, wires, rotor
-new PCV and hose
-checked and subsequently duct-taped the crap out of the intake hose
-new OEM air filter
-new throttle cable
-new fuel filter
-ECM is throwing codes 21 and 28 (bad O2's) Codes have been present for the past year, truck has been running perfectly.
-VAM checks ok per FSM
-IAC checks ok per FSM
I've read through many threads, but none match my symptoms exactly. Hoping someone could provide some real time help.
Thanks in advance,
-MK
