My car has been acting strangely, and it's been -40 here, and when I start it up it whines a bit, then once it has warmed up a bit it idles fine.
Then I go to drive it, and the car will run fine for ~5-10 minutes, at which point it may stop dropping the rpm (staying constant at 2k+ rpm) every time I shift gears, or it may start searching for idle. Fluctuating from 400-600 or 1100-1300 RPM. It gets worse if I continue driving, because a CEL light will come on and the car WILL stall, if I attempt to restart it the engine will keep searching for idle and usually stalls again very shortly.
Now, I noticed when the engine starts having trouble idling my heat goes ICE cold. It also gets frigid any time I'm driving over 60 km/h. I'm thinking these may be linked? I'm starting to suspect vacuum problems. I've replaced the water pump and thermostat, had the heater core flushed, and replaced the cam sensor. Help!
