OBD2 problems, Check Engine light on!
I cant pull codes! I've used all kinds of scanners including an auto enjunity, and none of them can connect! I'm at a loss! I've got power to both cigarette lighters and it seems I have it to the OBD2 port. With the cheaper scanners, I tried scanning it when it was running and it killed the truck so I know there is some sort of interaction, but I cant figure out what the deal is.
It used to come on only once in a while when the motor was cold, but now it is on all the time. It has a lope idle randomly at stop lights, if I let the clutch out and move forward a few feet it smooths out. Some times it runs just fine. It seems to do it less when my chip is in the stock position.
If anyone has any ideas I would be grateful! It has been about 2,500 miles since my oil change. (Rotella 15-40w and Lucas oil additive)
