i can restart the truck and it will idle fine for about 30 seconds and then it idles down and just runs terribly. its not drivable. CEL was on but i disconnected the battery and made sure all the sensors had a good connection. Now the CEL is not on and it still runs like dogshit
the CEL was your friend. I would get a scanner and try and catch a pending code. could be MAF, ECT, fuel pressure?..........I would start doing the maintenance on it.....clean the MAF, IACV, PCV, fuel filter etc. check the air-filter and intake and make sure nothing got clogged in there. also look for a cracked vacuum hose.
