The wife has a 2004 Pontiac Grand Am with the v6 engine in it. It Began to miss fire when going up hills or under a load. The first thing i did was to clean the Mass air wire. Then i replaced the fuel pressure regulator as the car was smelling of gas. I was assured this would fix my miss fire issue as well. No Joy! So still having the issue i thought i would ask on here. I used my OB11 scanner and i got a miss fire code. However it does not tell me which cylinder. I removed and replaced all the plugs with new, and installed new spark plug wire. Still no Joy! So i am seeking your advise. I need to get this corrected asap. Please help me out.
Also do you think i could use a spark tester and have the missing cylinder show up that way. It has a slight miss at idle. Almost none. Coil maybe? Thanks you folks
