My 94 acura vigor has a low idle once the car get normal work temp

Check the idle air control device-maybe clogged with deposits. The engine computer controls idle speed through this valve or motor. By increasing or decreasing the amount of air let into the intake manifold.

Why does Check engine light. Car misses or runs rough during initial warm up but runs smooth after motor temperature increases to normal operating range

If the check engine lite is on, check for applicable trouble codes. Around here some of the national brand autostores will check some codes for free. How long since a tune-up?
The basics for a rough idle, is to check for a leak of some kind, fuel--egr--vacuum, something of that nature.
If a temp issue, check coolant temp sensor.
I don't know year--make--model?

1962 Corvette. Replaced voltage regulator. Temp gauge now reading hot. Temp increases with RPM increase. At idle 180. Increase RPM, and Amp 220. Heat gun true 175. Help

What is the system charging voltage? An over voltage condition could cause this. Why not just hook up an after market gauge? The factory gauge is junk and as cheap as they could make it. And yes I have owned Vett's.

I have a 2005 grand prix gt temp guage reads normal and heat is on and warm when start driving heat gets colder or if i change to defrost its cold air doeasnt stay hot car doesnt over heat though changed...

The heating coil is probably getting plugged up. You may have heat at idle or slow speeds, but once you get going, there is not enough coolant going through it to stay warm. Get the system flushed or replace the heating coil.

Losing heat during idling

Check coolant level. As you increase rpms, coolant circulation increases, and vise versa.

My oil and water temp and pressure flucuate when it gose from idle to driving

oil pressure is going to increase with higher RPM's ,at an idle it should be around 20psi,at running speed the oil pump is pumping faster and it could clime to 60 psi.
water temp though you should check coolant level or think about a new thermostat
