1995 Grand Am hesitating on highway

1995 PONTIAC GRAND AM

I have a 1995 Pontiac Grand Am with a 3.1 V6 engine and Automatic trans and 124,000 miles on it. It misses when accelerating on the highway. If I floor it then the hesitation stops and it kicks in to passing gear. But if I slowly accelerate then it misses and the "service engine soon" light comes on and stays on until I shut the engine off. My son checked the codes and said it was a bad EGR valve. We then replaced the EGR valve but it is still doing the same thing. Does this sound like anything anybody has had trouble with? Thanks, Rick

Hi there I understand where your coming from. My 93 grand am was doing that about a month ago and now it won't go over 15 mph. So if you find out anything then let me know. I wish I could help you but I can't even help myself :roll:

I have a 95 Grand Am 6 cyl AT and I am having a problem with accelerating and stalling also. I have had the car for about 8 months and it seems to do better at times and then at times will cut out constantly. Anybody know how to fix this? I also had my car diagnosed and was told it was an oxygen sensor but did not need replacing.

I just serviced my 87 Grand AM. It's got a 3.0 V6 bored out.40 over. It would loose power and back fire. Check engine light would come on and stay there til car got shut off. I also got real bad fuel economy. Turned out it was the Crankshaft position sensor. I thought It may have been the Throttle position sensor but upon buying the manual and reading I found out I almost put a new $50 part on my car That It Didn't Need. I would check the Throttle position Sensor, The MAP or Mass Airflow(which ever your car may have), The Crankshaft sensor, and also make sure it's not time for a tune up.
Hope this helps.
