rough vibration from motor
My friend has an '02 93 that he just purchanced. It has 92k miles and has the 2.0 motor. He got stranded over the weekend and I went over to his place to help look at the car. After scanning the ECU it said there was a miss fire on cylinder 1. He had bad plugs, we replaced them, but that didn't help with the vibration. While the motor is at idle there is a bad vibration from a pulley and another part that we were sure what it is, the part on the left...it rotates a good 3/4" back and forth in balance with the wobbling pulley and that all seems in harmony with the rough motor. I have indicated in the diagram the pulley and the other part. He's going to get a service manual, but in the meantime any help is appreciated. Thanks!

Replace that. It's the tensioner pulley and it's a plastic piece of crap. http://www.eeuroparts.com/Main/PartD...px?id=5172309A

The pulley was shaking. I think it was because of the #1 cyclinder running rough due to the bad valve. Another friend who's a mechanic is fixing it on the side so it's not done yet. Once it is I will post the results.
