Question about 2004 Chevrolet Tahoe
While driving down the highway, my 2004 Chevy Tahoe displayed a reduce engine power message. The accellerator pedal at that point had no effect on the engine even though it was still running. My manual told me to check the gas cap by lossening it then retightening it. It corrected the problem for about 30 miles, then the solid engine light came back on with the same message. After going through the gas cap procedure again several times, the light and message warning went out. I made it home but am concerned about driving the vehicle for any distance at all now. What may be the problem. There are no service or warning lights that are on.
Have autzone check for any stored trouble codes, replace the fuel cap, make sure you have plenty of gas

SOURCE: check engine light
The gasket or large o-ring on the under side of the cap might be warn not keeping a tight seal. replace gasket or o-ring, or get a new cap, and see if that cures it.
