Engine Mechanical problem
2002 Pontiac Firebird 6 cyl Two Wheel Drive Manual 118000 miles
Good evening all,
I am a relative newbie to car repair and am having
some difficulty with my 2002 Pontiac Firebird. After
taking it to Advance Auto Parts and running a brief
free diagnostic on it. The code P0303 came up
indicating a cylinder misfire. I have since changed
replaced the spark plugs and wires and am still having the same issue. The second diagnostic at Advance
Auto Parts revealed a cylinder 3 misfire. Does anyone
have an idea what could be causing this misfire? Any help would be greatly appreciated.
have the same problem?
