learn to solder, fix the wires yourself; it's not that hard; and $200 is bullcrap because I they prob could have fixed it with less than $5 in parts. $200 labor doesn't happen that often. You got hosed, but the mechanic isn't breaking any laws. There's a problem with your vehicle, they attempted a diagnosis, it did not fix the problem. You're not paying them to fix the problem, you're paying them to find & fix the problem. They'll keep charging until they find the problem. I would imagine though that if there is a problem with with the computer, it wouldn't have read out proper codes to begin with. I would go pick up the car, say &@#% you, and drive the mother &@#%er until it stops running. Is $1000 bucks really worth turning a light off if the car is still running? It's not like we live in a state that requires passing an emissions test. Unless the light is flashing, it most likely won't cause severe damage to your car. It just won't run as effecient.
