Is there a fuel filter on this suv

Yes, if you didn't see it from the fuel lines coming from the tank along the frame rail, it's integrated into the fuel pump which is inside the gas tank. I believe 04 was the last year of the external fuel filters for Envoys and Trailblazers.

No codes, low idle, stubble during acceleration and when A/C is on.

Shotgunning this problem by replacing random parts will only cost you extra money. You need to have a technician diagnose the problem using a high-end scan tool to read the data that the computer is collecting. Also, the fuel pressure needs to be checked.

GMC 2003 Envoy SLT my back break lights and tailbar lights stay on when I turn the car off. What could the problem be?

This most likely is a bad or incorrectly adjusted brake light switch. The brake light switch is located under the dash next to the brake pedal arm.

Is there any greasing nipples for the GMC envoy slt 2003 ? & If any where are located? squeaking noise at the left front

There are no grease fittings on most of today's cars. The squeaking noise may be coming from a dried out suspension bushing.
