My car began to run hot around May 07, took it to the Napa Auto Care in June 07 for repairing intake manifold. I have had the intake manifold changed twice within a month of each other, I have had the water pump replaced and just recently had the head gasket replaced and pressure checked and shaved the heads down. The car no longer runs hot but has a rough idle and the check engine light is on. Please help, any advice would be greatly appreciated!!! I have spent $3000 on this car in the last couple of months, its not worth it anymore, still paying a car note
