bank. Ck wires, plugs, injectors,coils, replaced intake gaskets,map sensor, 4 o2
sensors,ck compressions, ck fluid pressure clean gas tank, ck for vacuum leaks, been to
two Chevy dealer to be worked on. They don't seem to do know what wrong. They
haven't fixed it . One dealship took back twice. They said it could be this and every time
it cost me money and truck is not fixed yet. Does anyone know who I can talk to to help
me fix my truck. I have spend enough money to buy a new motor.
