2002 Chevy Impala Misfire??
I have a 2002 Chevy Impala and it seems to have a misfire, i took it to autozone for a free diagnostics, and they said i had a misfire on cylinder 5, i changed all spark plugs and wires, no help, the check engine comes on and stays on at idle, but when i get goin it starts blinking, i have no other ideas what the problem may be, its a 6 cylinder 3400 injected engine, any ideas on how i can fix the problem, or what it might be, i added some fuel injector cleaner, no effect yet, any help would be great, thanx.
