Q: Car labeled gross polluter
My car runs great, but has been tagged a gross polluter. I rebuilt the carburetor, and it looks good on the low side. But on the 2000-2500 test, it's 565 and should be 150. The car does not smoke or use oil, and the temperature is always at halfway point.
The carburetor may need to be adjusted while the gas analyzer is monitoring the levels. If the adjusting does not fix the problem, then the converter may be defective and need to be replaced. I recommend that you have a mechanic, such as one from YourMechanic, come by and check your car for you.

When idling it over heats but when I press on the gas and bring the rmps up they suddenly drop and my car cools down?
When you accelerate the engine, although you are adding heat, the water pump also spins faster increasing coolant flow through the engine and to the radiator. Perhaps there is an issue with the water pump and/or the water pump drive...
