1. You need new rotors, yours are warped or have high a low spots. You can eather get them cut for cheap or just buy new ones which would be the best bet. I have 2 cars that have the same problem and I just really never have the time to cut them.
2. You might need a new temp gauge. not 100% sure on that problem.
3. You might need a entierly new odometer w/ the speedomoter and all that. I forget the correct name.
4. I dont know what your talking about really.
5. Sounds like your suspension is bad and the wheels are rubbing on the wheel wells or the car grinding across the ground.
6. You need a new gas tank or get a gasket replaced.
7. Again is sounds like your tranny is getting bad. On other cars your tranny does that when its low on tranny fluid or becomming a piece of crap.
