Question about 2001 Pontiac Grand Am SE

2 Answers

Hesitation and slight rpm drop at idle and while driving.

I have a 2001 pontiac grand am 3.4 auto. For about a month now, it has had some hesitation issues. It happens at idle and under load while driving. When idling, when it happens you can see the tach drop very slightly then come back up, maybe a drop of 50rpm or so. You can hear it in the exhaust when it does it. The air filter, plugs and wires were replaced within the last two years. I'm wondering if it might be a fuel issue, perhaps the filter or FPR?

It is possible there is a soft vacuum line. try looking behind the maf sensor [attached to the air filter box] on the right side near the plenom next to a blue connector. it's a small piece of hose that is looped from one vacuum circuit to another. I have found them to get very soft and **** air.

Testimonial: "The problem seems to be less consistent now. Guessing maybe there is still a vacuum leak somewhere else. Thanks for the tip :)"

What causes hesitation in 3rd, 4th and 5th gear?


I would suggest that you take your car to O'rielly's or one of the larger auto parts chain stores and have them connect the diagnostic reader to your car. It sounds to me as though you are experiencing something to do with the cars computer and the way it is reading it's sensors. They will do this for free and then tell you what the error codes mean, if any. If you do receive error codes, chances are that is your problem and you will then be aware of what it is and what it will cost to clear it up and not have some mechanic charging you for his time doing exploratory diagnostics and charging you an arm and a leg just to find out whats wrong.

I have a 2001 Grand Am 3.4l V-6. I have replaced spark plugs, wires and coil pack. Still has rough idle and hesitation during driving.


check the plug where the air intake connects to the engine. i had a loose connection in mine, it cost me an alternator that i didn't need. the wire also caused rough shifting.

Engine hesitation, the trac off light comes and car hesitates.


This is just a shot... Get a Can of "SeaFoam" and pour it into your gas tank with a full tank of gas. Then take it for a "Spirited" drive on the freeway or highway for at least 30 minutes to an hour. (Longer is better) i have had many cars with a little hesitation or sputtering fixed with this awsome product. it is a very powerful cleaner that has chemicals that other brands simply do not have. Conditions should have improved after your 1 hour drive. and will continue to improve as you continue to drive with that treated tank of gas. If the problem persists then you need to get the OBD trouble codes and let it direct you to the failed part. At least you would rule dirt "Out of the Question" (Also read the can for other things that Seafoam can fix on your car and how to use it) also does wonders for a couple cap-fuls in the lawn-mower...Chainsaw....Snowblower...etc i Hope this helps you out... Good Luck!
