Apparently there was oil getting all over averything. This caused the Throttle Positioning Sensor to fail. I was going to work and it seemed like I had to press harder on the brake to get the car to stop. Got to a red light and put the car in neutral.....RPM's were in the 3000 range ( should normally be less than 1000 ). Had to finish the drive in low gear. After work the car ran fine. Took it to the local shop the next morning. In addition to the valve gasket replacement and the throttle body cleaning, I was advised to get a tune up. Since I had only owned the car for several months at this time and didn't know how long it had been since the previous tune up, I decided to go through with it.

After all was said and done, I was handed a bill for $803.04

Labor = $274.87

Parts = $500.00 ( unusually round number, don't you think? )

Tax = $28.17

That was a month ago. Occasionally, I still get the "Service Engine" light. Usually comes on right after a start up, lingers for a few days and then goes away while driving. Each time I bring it in to see what that light is about, they tell me the same thing.....something wrong with the # 2 Cylinder. The car runs fine but the light still persists. Instead of "Service Engine", it should say "$$$$". The longer you wait, the more dollar signs get added to that light until the final light appears....."FOR SALE".
