Title: Extreme engine vibration
Post by: btwodu on March 04, 2007, 03:02:34 PM
I changed my O2 sensor Friday and began to notice a slight vibration, but nothing to worry about.
 
Saturday morning I start the car and it feels like the engine is shaking the car to purposely rip the doors off. Outside of the car, the engine just shows a slight movement. Inside the car it feels and sounds like the car is in a washing machine.
 
There is not a noticeable change in acceleration or performance in general. At low RPMs it is the absolute worst. After I get to 30+ mph it gets better (slightly bearable).
 
Where do I start. Could it be a timing issue (checking on that today hopefully), motor mounts, my imagination, or what?

In addition to this, I finally was able to locate my timing marks so I could test out my timing light. They arestaring at me from UNDER the car. I am sure that could make timing a little difficult.

My Harmonic Balancer is ka-put. I guess since I have everything off its a good time for a good cleaning.

Didn't think to take any pics. I took it off last night. Have the 4 pulley bolts soaking in WD-40 right now. The rubber holding the balancer together basically ripped off. Luckily I only drove the car a few miles before stopping it for the repair. IT was definitely a shaky ride.
