Two months ago i ran out of gas in my 03 tahoe. it failed inspection yesterday because the computer did not reset. i drove it 60 miles without stopping (like the tech suggested) but it still didnt reset. the check engine light never came on and it has been running fine since i ran it out of gas. any other suggestions besides going to the dealer and spending a lot of money on a car i was planning to sell in july?

First a question - is the truck engine running a little cool ? You should be able to tell this by the tempature gage = it should read about 200 degrees. If it's not reaching proper tempature, the monitors may not reset [ this could be happening without setting a running cold code ], running the truck with a scanner attached will give a proper reading. If everthings ok with the tempature then continue on. --- If the computer codes aren't being erased when they scan it, then either you are looseing power to the computer when the igntion is turned off [ the shop should be able to dertermine this easy ], or the computer may be faulty. The monitor for the o2 sensors or the converter may not reset if it had a faulty o2 sensor [s], it wouldn't affect the e-vap monitor. I'm afraid your going to have it checked out in futher detail as there are several items involved. First a question - is the truck engine running a little cool ?
