I know i'm one of the few with a 5cyl engine here but...

I just came home from a friend's house just now and when I first turned my car on my car started to wobble a bit in a fast manner. Its hard to explain how it felt, but I guess it seemed like every time one of my cylinders fired it shook the car. i revved it a bit and it only increased the frequency in which the car shook. for the first maybe 10 minutes of the drive it was like this - on the freeway on ramp i tried to push it a bit, but it didnt boost at all, just made a spooling noise - and the car wobbled like it was high but as soon as i let off the gas the car was as smooth as always.

when I got off the freeway it didnt do it at all, and the boost came on just as strong as always and there was no buck at all... what could this be?

EDIT: when the car is idling with the hood up i hear what sounds like a leak coming from the throttle body/intake manifold area but I dont see anything and I dont know where to look. I took this picture to try to explain to you guys where the wierd sound is coming from.

 

I found out my cylinder #2 coilpack was out, ordered a replacement and will be fixed tomorrow. I will no longer have to drive a 4cylinder car!!

just so everyone knows everything is alright

 

Glad to hear everything is cool.
