Question about 2001 Pontiac Grand Am SE
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 :)"
Change the fuel filter and if that doesnt work go have a mechanic look at the fuel pump
