i have a 99.5 A4 1.8t.......... but i'm asking about a 2000 jetta 1.8T
i figured most things will be the same except they have the engine pointed the wrong way...anyways, i know i can get good answers here if there are any.

the car belongs to a girl i know who just figured out which pedal was for the brakes so info is as good as i can get.

its got a misfire at idle and the brakes suck, and when i had her get it scanned )obd II) it came up with a misfire on 3 cylinders. sounds like a vacuum leak but it doesnt happen all the time....sometimes it run normally.

then twice on longer trips she said she would have the pedal to the floor and the car wouldnt move. like actually broken down. then it clears up and she drives on.

i know its a shot in the dark but maybe someone has half a clue what's goin on cause i wont get a chance to get to the car for a month or so and because it's not "broken down all the Way": she won't take it to anybody.

thanks
