well the code was a prImary circuit malfunction,
and a secondary malfunction.
the secondary one I have had eversince the gas gauge went nuts.
but the primary one is new.
drove it around for a little while tonight and no problems, as of yet.

maybe it was just a fluke thing. almost like it went into limp mode like the 03-04 trucks do when the computer senses something wrong. beats me.
I do know that GM needs to hurry up and find a permanant fix for these damn fuel pumps. I dont wont to blow $400 just to have it go out 6 months later

 

ever change the fuel filter?

 

yup my truck had a period where it did the same thing for a day or two... i was gonna take it in but then it just stopped and went back to normal, just a fluke thing.

but i did take off my intake tube later that day, and found carbon build up in the tb
