I know it is the summer and car tend to overheat but my car the temp gauge will go up and down depending on if i am stopped or going. When i start the car it sound like it is not getting enough fuel but after letting it run it stops and runs like normal. when i stop my car the tachometer goes up and down from 500 to 2500. not so much different or interesting as far as the sounds the car makes.

any help is better than no help

thanks

Top off the radiator and reservoir with coolant and then bleed the cooling system.

 

I did that and no issues for the week until yesterday that same thing happened and then tonight it went to the top of temp gauge before i got home. i turned it off let it cool checked if fan can on it did and is good. and then the check engine light came on?

where to go from here? thanks RonJ

 

I had the same problem. Checked both gaskets and both were leaking. Tstat gasket and front water neck gasket. Filled up and purged air out of the coolant system. My thermostat stopped working and caused the leak. The air bubbles usually cause the erratic idle.

 

Turn the engine off before the temp gauge needle gets close to the red zone. Otherwise, you'll destroy the engine. Have you looked for coolant leaks? You should probably pressure test the cooling system in search of a leak. Also replace the thermostat and bleed the cooling system again. Other possibilities are a bad radiator or blown head gasket.
