2008 z71 flashing cell
OK about a month ago my cel was flashing and my truck
ran rough toomey it to the dealer he said I had a misfire on
#7 and#1 cylinders did a tune up and also changed.the
valve cover on the driver side it was recommended by the
dealership so I did (I did all the work myself ) Now my truck
is doing the same thing so I pulled the plugs to see if any
were fouled out and nope all looked good haven't got the
computer read for the codes yet seeing I work nights I am
gonna have it done over the weekend dies any one have
any suggestions on what to do?
