1999 Z71 ext cab 5.3. Having issues
My truck has been having a rough idle for the past few days so i ran some lucas injection cleaner through it and no difference. So today i put my truck on the scaner and it put out 3 codes. First code said. Bank 1 lean, and Band 2 lean. Then my third code was evap control flow low. If someone could tell me what the codes mean it would help alot! Thanks in advanced!

I am not sure what the evap control flow low means but I can tell you for bank 1 and 2 lean means the motor is running lean. You are not getting enough fuel to the whole motor bank 1 is the left side of motor and vice versa i believe. I can tell you my truck threw that exact code and it ended up being fuel filter. I hope that helps out some and let us know what happens

I had a Suburban do that and it ended up being the intake manifold gaskets. It was worst in the morning when cold then got better as the engine heated and the expansion closed the gaskets off somewhat, but remained rough idling, up then down almost falling on it's face then recovering itself.

Well i got a new fuel filter then the damn gas line from the filter to the rubber line snapped. So iam hoping i can pick a new one up or im gunna have to make something up. But im crossing fingers that i can just go get a new line.
