WILL A BAD HEATER CORE MAKE YOUR CAR IDLE UP ON ITS ON AN CUT OFF ?

1997 Buick Park Avenue • 170,890 miles

Yesterday it drove fine after I put new intake gasket and vale cover gaskets and a tune up. I would say driving for like 30 mins or so the front window kept fogging up then I notice a puddle of coolant on the passenger side floor. I got back home started my back up an it idled up on its on an cut off but starts right up everytime. Oh yea and I was smelling burnt coolant

If your low on coolant, this can effect engine performance. Did engine get HOT from low coolant?
