Message: [QUOTE="seabee15, post: 1417995, member: 23895"] This morning it was 36*F. I cycled the keys twice (until I heard the priming pump stop)with out starting- it cranked until it sounded like it was going to die - cycled it a third time- started up quickly. A new discovery- I scanned the truck yesterday afternoon and the P1670 "EF signal not detected" code came up. I cleared the code and drove the truck no problem. Scanned it again- no codes found. This morning - I performed the above starting sequence- scanned the truck as I was driving, P1670 came up again. Cleared it while driving- scanned it 20 miles later - no code. Mind you, I'm using my superchips programmer to run the diagnostics- I don't have the money for a AE and I just bought a ELM 327 that will be here in a week or so.
