Check Engine Light, steady and flashing?
Hi all,
Was away for the holiday and the truck sat for a week. Went to start it last night and battery was dead (think I left the XM on....oops!)
Anyhows, jumped battery this AM and have new problem. Check engine light stayed on, truck is running like it has a potato in the tailpipe, (rough idle, vibrations, seems like it is missing on acceleration) and when I get up to 40 MPH or so check engine light starts flashing and then goes back to steady on. It rained a lot the past few nights, don't know if that is a factor. Also, truck was on empty so I dumped about 4 gallons of gas in it after I started it. Gas was a few months old at best. Just thought I'd mention it....
Truck is a 2000 3.0 / 5 spd / 4 X 4 / Super Cab with about 106,000 miles. It was fine when I parked it (of course
)
Any ideas where to start looking appreciated!

Went to Autozone this afternoon, engine misfiring on # 5 cylinder. Spark plug wire was bad (boot had a rip that must have been arcing) . Will change them all since they were the originals. Running great now, thanks for the tips!

You can reset the codes with a scanner, or pull the disconnect the battery for about ten minutes.
Be aware, if you go the battery disconnect route, the truck may run a bit odd while it "relearns"...
