Car is idling semi-weird with hesitation

[Iamjohnhayes]

Ok 2 things before i start:

1. the car is still NA2. this all started when i got out of school and started my car (at midnight) so i haven't checked anything yet.

So i get out of class tonight and go to start my car, first the car starts but the idle doesn't want to go above 800 rpms unless you push the gass and there is a slight "stutter". So I give the car some gas pedal for a few seconds and its idling between 950-1100 (normal for my car). So i just think hey thats weird ok w/e. then i go to back my car out after it warms up and it hesitates or stutters between like 1200 and 2000 rpms. Also at the last light i stopped at before my apartment the idle started to "roll" kinda like when the car is warming up. it went from 1000 rpms up to 1500 and back down and back up a few times. then as i am driving through my parking lot my car almost dies as im rolling over a speed bump.

Recently the only things i have done was loop out my charcol canister in my never ending search for my vaccum leak that makes my car idle at 1100 rpms. the car started fine after i did it too (about 2 days ago).

So any ideas on what to search for would be awesome.

check for loose or damaged plug wires. That can cause an intermitant miss.

you could also check the TPS on the side of the throtlle body. sometimes those screws will come loose due to engine vibration. Make sure all of your vacuum line clamps are tight too. I went through hell with my girlfriends car with that. one small leak will make you think your car is on crack!
