Vibration With Throttle
I just picked up a 2003 SI and have a quick question. At around 50mph there's a decent vibration that I thought may just be a wheel out of balance but I noticed today it only does it if I am giving it gas, the harder the gas the more vibration but it eventually sort of fades off closer to 75mph. If I push the clutch in or take it out of gear it goes smooth. Any ideas? I'm going to jack it up tomorrow and have a look, if nothing sticks out I'll take it to a shop but I wasn't sure if there's something that immediately comes to mind for these cars with this symptom. It drives straight, no pulling but I did notice sharper left turns at more than a parking lot speed you can feel the vibration if you give it some gas.
