So truck is giving me 18, 33 and 88 CEL codes (KOEO). Truck won't do the KOER (engine running) test. The tester beeps once then flashes 98 (meaning can't run the test) over and over again.
I recently replaced the EEC relay hoping that would help. Didn't. I had the ICM checked at autozone - passed 4 times in a row and got nice and hot.
The truck runs great, I'd just like the light out. I'll fiddle w/ the EGR soon.
What would cause the truck to be unable to run the engine running test? That kinda bothers me more than the light just being on.
