possible early 07 IL5 motor, vibration

[H3Wolf]

so I have been kind of annoyed of the motor vibrating, but it got worse till this morning cause last night. I replaced all the plugs, air filter, did a fuel injection cleaning, and replaced the belt tensioner. and the vibration got better. it only vibrates at idle, as soon as I rev the motor or start driving the vibration stops. and feels great. I feel it might be the harmonic balancer, because before I replaced the tensioner it looked a little shaky even in the few rare moments that the motor didn't vibrate the balancer looked a little off. has anyone had this issue at all? video will be posted after I get home from work today.

Yes...very recently (last week) someone posted a thread about their damper coming apart at the rubber ring.

FWIW, most vibes can be traced to defective coil paks. They don't just "fail" and quit. Instead they grow weak and don't put out the spark they should. If you have over 80k miles, coil paks are probably due.

yea it actually just hit 90,150 miles no thanks to my wife's friend barrowing my H3 while I was gone for 9, I was at 70,500 when I left, came back and boom, 80,700 miles, and she only had it for 3 months. but anyways back to the main problem. I will start looking into the coil paks and see if any are bad

Yep that was me doing the harmonic balancer swap. It helped stop most of the vibration. Take a look at your engine mounts too. Mine are cracked at the rubber insert. Doing the engine mounts this weekend. 231000 miles on the H3

Yea, I just have to find a place to find parts without breaking my wallet LMAO

Rock auto is where I got my parts.

I'm curious to see how bad your guys vibration really is, I've always been under the impression that the i5 is characteristically a vibration prone motor due to the imbalance of cylinders

I was told the 06 to early 07s had bad balance shafts and harmonic balancers
