If the oil is low in your car, it can eventually cause your car to stall and not start. It can also kill your engine.
Only if it's so low that the bearings ovrheat and sieze the engine.
The heater will stop getting hot when you're low on coolant. If the coolant is low enough the engine will overheat and it will be severely damaged.
It sounds like your engine is not getting enough fuel.
engine stalls at low speed
When the oil light is on, it means you have low oil pressure. This can be caused by low oil level. When you first start the car, the oil light will come on momentarily, then turn off to signify that proper oil pressure has been reached. An engine knocking usually indicates that the engine is about to stall.
Does it say Engine Prot? means that you might be low on fluids such as coolant and the longer you run with it it, it will start to slow down the engine until u stall out....happen to my cat c7 in my freightliner. and it turns out i blew my cooling system.
mine stalled randomly, and it was a vacuum hose on the top of the engine, it got old and hot so it melted and was clogging the engine at low idle. replaced the joint with a pvc part i got form the autopart store. still works today.
Perhaps the A/C is drawing too much power from the engine, could be the engine is idling too low.
I really doubt it's the tranny making your car stall, it's either carburetor problems or the idle is set too low.
sounds like the idle (the speed at which the pistons in the engine are moving when it is just sitting there) may be set too low.
Had a Jeep in the shop here with that problem last week and it turned out to be low fuel pressure. Try running a fuel pressure test. The Jeep would idle ok but when you tried to accelerate the engine would stall.
If the engine runs cold you might try replacing the thermostat. I had a similar problem with a Plymouth van, at low rpms, turning corners,,, it would stall.
