Question about 2005 Chevrolet Impala
Check and replace the plugs and see if the Spark plug wires need to be replaced too. Make sure the wires don't have any burn marks or arching on the exhaust manifold. The other thing to look for is dirty fuel injector and fuel pressure. Check the fuel pressure at the shredder valve, upon start up there should be 60psi to 65psi and when the engine is running it should drop 5psi. Good luck and hope this helps. keep me posted be glad to help.
