Reduced engine power may be many things but the reduced engine power will also throw a trouble code. Get that information to diagnose your problem. If the check engine light is on steady it is usually OK to drive however if it is flashing you must shut the engine off. A rich running condition will cause your catalytic converter to overheat and melt.

Where is the oil pump on a 02 gmc envoy?
In 02, the Envoy was a trim package for the Jimmy.. it didn't become a separate model until the next year, IIRC. So, you would have the 4.3 Vortec, and I have some unfortunate news for you - the oil pump is an integral part of the engine. By which I mean, it's inside the engine, and, to replace it, you'll need to pull out the engine, remove the oil pan, and access it that way.
