My motor mount broke.
My fog lights were cracked when I got the car - common problem.
Engine coolant temp sensor was replaced.
Some ground wiring was bad and was replaced.
Air/Fuel mixture problem.
The car is very comfortable.
Although it lacks low end power, a supercharger pulley, performance computer, and intake really do help.
It handles like no other car, it is, in my opinion the best handling car.
Currently my car is getting too much gas and not enough air, making it run rich, and finding someone to figure out what is wrong with it has been horrible.
The problem with the fuel mixture may be that you have a bad oxygen sensor. The one on my '89 Golf went out and it had the same problem. One way to test this is to unplug the sensor and then the car should run better.
