My car has 180 miles.
There is a technical bulletin out for your 1999 Tahoe put out by Chevrolet. It's number 00-07-30-006, 87-71-63, calling for the reprogramming of the transmission/engine program. You will need to have the dealer reprogram the vehicle for you.
Before you take the vehicle in for reprogramming have any oil-bath type of air filters removed. The oil from these type filters will contaminate the mass air sensors and cause various drive symptoms and may be one of the causes of this concern. Therefor I'd also recommend having the mass air filter and throttle body cleaned. Good luck.
