Left three ugly oil stains on my driveway with his old work van. He was unsuccessful in diagnosing and repairing the vehicle and left with a couple of guesses of what the problem might be and an over $800 estimate for the "might be" fix. The vehicle was not giving any Engine Codes for diagnosis. The tech said he could do nothing without codes. At any rate, since my vehicle has the stalling issue and safety is a factor, I had no choice but to continue to research a remedy for the stalling. He suggested timing and a crankshaft sensor for the possible remedy. After checking the issues on user forums and reviewing the systems involved in the vehicle, I repaired the issue myself with a replacement Throttle Positioning Sensor. No more stalling. Now, all I have to do is find a way to remove the unsightly oil stains from my freshly pressure washed driveway. $80 spent for nothing but grief and some hours recleaning the driveway. (if it can be cleaned). At least I was able to fix the vehicle!
