Unhook your batts for 5 or 10 mins. Or get a code reader. AZ will not clear codes for some reason. Best $200 I spent for a code reader

Ok. Just wanted to make sure that the vehicle computer wouldn't have an effect on the problem continuing. Thanks. Hope the filter does the trick.

INNOVA 3160B ABS/SRS+ Professional CanOBDII Diagnostic Code Scanner with Enhanced Live Data : Amazon.com : Automotive INNOVA 3160B ABS/SRS+ Professional CanOBDII Diagnostic Code Scanner with Enhanced Live Data : Amazon.com : Automotive

That's what I have. It does a lot more cars than listed, you just have to play around with it. The SRS most likely will not work on your truck, it does not on the 06 LBZ we have, but it did on my 05 suburban. But the live data works on all my cars, Dmax and BMW. Works on my 00 F550, but very limited. Best part about it is you can scan for codes with out a CEL. The F550 kept throwing low injector pressure, but not a CEL. Who would have known otherwise.

My 07 Lbz did this the other morning when it got down to 5 degrees. Changed fuel filter and dumped 911 in the tank and it ran like a top again. I imagine it was just gelled or the filter was plugged.
