Those are the codes that came up by cycling the key 3 times. Now for a great description of what my truck sounded like! LOL

-Sounded like an injector knock. Maybe only on one cylinder.
-Did this twice out of last 30 or so starts. Right after start up while engine was warm.
-Real touchy fuel pedal.
-Shut down engine and re-started. Both times it was hard to start.
-After turning engine on and off a few times everything was back to normal.
-I have an edge juice with attitude with the hot program installed. Did this on level 4 and stock.
-I will be yanking the juice with attitude off soon and have ordered a smarty jr. See what codes come up then.
-Will also be cleaning the battery posts and checking grounds.
-Water in fuel light never came on, and everything looked great when I took a sample off the fuel filter drain????
-205,000 kms so no warranty anyways.

What do you figure?

Thanks.

You may have a shorted wire going to the HIGH/LOW pressure switch on the A/C. That wire provides the 5 Volts to the camshaft sensor. Pics are in the thread on where to look at by A/C compressor.

I read that post about 3 months ago! Totally forgot about it. Sounds like it might be my fix! Thanks a bunch.
