We have a 1995 Pontiac Grand AM. It started acting up about 2 weeks ago.
Total loss of power. I talked to my brother (who worked as a mechanic for
several years). He came and looked at the car. He found that #1 cylinder
wasnt getting fire. His first suggestion was to replace the ingination
coil. We did that with no diffenence. He had disconnected the injector, no
difference. We switched the spark plug boots, again no difference. He then
suggested that we get some injector cleaner. Did that, no difference. But
the car did run. Just very rough because it was only running on 3
cylinders. The other day, the car just stopped. Quit!! Again my brother
came and looked at the car. He is stumped. We have replaced the fuel
filter, camshaft sensor, spark plugs. We have checked before the car quit
running the compression and it was fine. Its getting fuel, gettig fire
except at #1 cylinder but will not run. Turns over fine. Tries to start but
wont. Also when we have this last trouble, before it stopped running, it
did backfire. And while trying to get it to start, it has backfired too.
Exactly which trouble codes did you get when retrieving them? I am interested since they will give a starting point on how to troubleshoot.
