Gauges goin crazy on dash All my gauges are out of wack, it is getting colder here in idiana, so I do not know if that has to do with it, but my MPH, says I am going 150-200 in park, rpm tack vibrates a lot does not stay steady. Computer problem?

Common issue. You're getting some resistance issues from your BCM wires rubbing on sole metal behind the glove box. Wrap 'em up real good, and you'll never have that problem again.
There's a sticky over on ls1gto if you're wanting to check out a more detailed write up with pictures.

Could be this old TSB also.
Speedometer Erratic Movement, Fuel Gauge Does Not Go to Full After Filling, Engine Coolant Temperature Gauge Reads Hot and Coolant Temperature Light Illuminates (Reprogram IPC) #05-08-49-003 - (Jan 20, 2005)
2004 Pontiac GTO
Built Prior to VIN Breakpoint 4L296011
Condition
Some customers may comment on one or more of the following conditions:
• Speedometer jumps erratically. Gauge may go up to 200 MPH or not return to zero.
• Fuel gauge does not move off empty when tank is full.
• Engine coolant temperature gauge reads hot and coolant temperature light illuminates.
These conditions may be intermittent.
Correction
Technicians are to reprogram the IPC with an updated software calibration. This new service calibration was released with TIS satellite data update version 1.0 available January 10, 2005. As always, make sure your Tech 2® is updated with the latest software version.
Important: Vehicles built after the VIN breakpoint must have the IPC replaced to correct these conditions
