SOURCE: E-vac system on fuel tank

P0452 = Generic Evaporative Emission System Pressure Sensor/Switch Low Input.

Since you have a 2004 Envoy, you probably have the dreaded bad 2004 PCM. It is part of the emissions system so it is covered under the emissions warranty (although it's already 2009 and i'm not from the USA, so I'm not aware if that's still applicable).

But in other words: contact your dealer !

My 2004 Envoy SLT guages are working then they aren't. Mainly the speedometer and fuel hand.

More than likely the stepper motors that drive the gauges are going bad, this a common problem on these instrument clusters. There are several repair services listed on E-bay who repair clusters, if you are willing and capable of removing it from the vehicle.

Started with fuel gauge now oil pres. gauge , sometimes tach , these gauges bury themselves around clockwise and don't read properly. Sometimes at highway speed say 50mph the tach is reading 6000rpm, gas...

The gauges in the cluster are driven by stepper motors, these are known to fail. There are vendors on E-bay that offer services to replace the stepper motors. This would require you to remove the cluster from the truck.
