for the heater just to cut out from hot to cold then kinda heat up again slighty then drop again would be lack of antifreeze and water in the radiator. check that first. . check it... when it the car is cold open the radiator cap and look inside for fluid usually greenish in cool. if no fluid add a 50/50 mix of water and antifreeze to fill. check fluid levels again the next day ....there may be a possible leak.
It is important to maintain the fluid levels while owning a car. A 2000 Chevy Cavalier can use 5W30 and 10W30, depending on where the driver lives.

Replace the fuel filter, that is a good place to start.
I'd check the coolant level first, then the thermostat.
Unplugging the coil wire and not grounding it, yes that can damage the coil.
Wheel bearings and allignment. Can be tires as well and sometimes even a bad motor mount.
The expected fuel economy on a manual transmission 1995 Chevy Cavalier is an average of 26 miles per gallon. In the city, you can expect 22 miles per gallon, while averaging 33 miles per gallon on the highway.
