03 Z71 STARTS BUT DIES.

2003 Chevrolet Tahoe • V8 4WD Automatic • 239,000 miles

I have a 03 tahoe. Z71 it well start but dies rightaway. The display reads reduced engin power. I looked this up its a protective defalt for if the engin over heats. My tahoe is not over heating

It may be a default for one of many conditions. Usually it is relevant to a fault with the electronic throttle. Have you been able to have it scanned for fault codes?

You do have a message for engine overheat, the engine power reduced message is indicative to another fault.

That is one of the possibilities. What code(s) did you get?
