So I got stuck in DC traffic for 2 hours tonight. While I was sitting there my car started to shake a little. It was a very slow shake and was actually in rhythm with the exhaust. Then when I went to pull away, I had a big lack in power. This happened a few times, but since I got out of traffic its been fine. Any ideas?? My car is an 07 GT stock other than the axle backs..

 

i could be wrong, but if it was in rythm with the exhaust i would possibly say u didnt have all ur cylinders firing, how much do u drive? do u use cheap fuel? it could be ur spark plugs... i dont know for sure, but thats what i would initially think.

 

Possibly a fouled plug or dirty injector. Could be fuel but it sounds like 1 cylinder was acting up. I'd put some fuel system cleaner in the tank and take her out on the open road and open her up a few times, then just keep an eye on it.

Also take note of your idle speed if it happens again.

 

Thanks guys, that's what I was thinking too. I happened within 20 miles of fueling up and it definitely sounded like I was down a cylinder. Luckily I didn't fill it up so I think I'll go fill it up at the shell station I normally use and see if solves the problem.
Thanks again.
