I have a 2001 Chevy Tahoe with 87,000 miles. Within the last 4 to 5 months the SUV has been stalling will at idle or turning in a parking lot. It runs good while driving at a constant speed. However, I do notice the car surging or the RPM jumping as we are traveling. On long trips (250 miles) with AC going, at the end the check engine light will illuminated for a couple of days then disappear. This only happens on long trips. I have changed the fuel filter, air filter, PVC valve, and battery. The only thing I have not changed is the spark plugs. The last couple of days after getting the PVC valve changed the car has died three times each day. I can place the car in neutral and it starts right back up again. Do you have any ideas or suggestions? Thanks for the help.
