    2003 A4 shaking

    Guest-only advertisement. Register or Log In now!
    I'm trying to figure out why my car shakes, it only really does it when I'm cruising at around 45-60 mph slightly letting off the gas while still maintaining speed. I can increase speed gradually and the shaking stops, steering wheel shakes and a slight vibration in front end. I've replaced the lower rearward control arm, both upper control arms, outer tie rod end, and wheel bearing on passenger side front. The rims and tires are in great shape and drives straight down the road. It has the CVT transmission with a 1.8T, 132k miles. Could a snub mount cause that vibration when slowly easing off the gas, motor mounts aren't leaking and alignment is spot on?

    I just replaced the drivers side, it was a lot worse when I purchased it, didn't think I'd make it home, 60 miles away.

    My b6 was doing this for awhile, and it ended up being misfires. See if it vibrates when you let of the gas. If it doesn't it's probably misfiring

    The only code thats on is the P0420 due to a test pipe on it with no rear 02 sensor spacer.
