probably bad headbolts that have stretched. have a radiator shop pressure test the system to see if coolant is escaping into cylinders.
Throttle position sensor
if it smells like antifreeze inside the cockpit then your problem is the heatercore, since you can't see it.
A leaking fuel pressure regulator is the most common cause for a rich condition on the Olds Aurora 4.0L V8. -------------------------
a cracked head
If there are no visible leaks....a blown head gasket.
Cracked head or a blown head gasket. good luck.
yes..a bad oxygen sensor can/will make your car stall at idle speed
on my 97 the cause was the cam position sensors, there are 2 it cost me $500 at the caddy dealer
Could be,blown fuse, bad blower motor, bad switch, bad resistor,
Yes. Antifreeze is actually pumped through the intake manifold. If the gasket is bad it is possible that it leaks out
check the wires, if they are crossed up you get bad ilding. my aurora was idling around 1500 rpm's, but after having all the spark plugs and boots replaced it went back to around 600...see if that helps
Fuse, wiring, connector, drivers side window control switch.
