Heating / Cooling System Malfunction When stopped When warm
Q: My 89 dodge diesel tries to die at stop lights, with the air conditioner on. It never dies it just shakes and the oil pressure falls to about 10 psi.
A: Check transmission lock-up to see if it will stay on when hot.
Q: When I start my car, the alternator gauge goes down to the negative area, and when I start driving it goes fine.
Sometimes it doesn't go into the negative part, BUT my car still chugs and stalls. It's usually ok in the day but not at night.
Could it be that I don't have the right battery?
Also, there is a certain hose that goes from the engine to the carburetor that is almost falling off. I think I read somewhere that isn't hooked up right it'll stall in the cold. Sound right to you?
A: Yes, that sounds right to me. Especially if it's both cold and damp where you are.
This often causes icing of the carburetor.....
The hose I think you are referring to brings warm air from the exhaust manifold to the incoming air.
This of course warms the air as it enters the carb, and it helps.... Ed
