SOURCE: why does reduce engine power light comes on chevy

That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.

Reduced power is a mode the engine goes into when there is something wrong with the cooling or the firing. If the engine gets to hot it uses the pistons to air cool. This of course is not a for sure but where I would start.
