Why does my automatic car stall when I come to a stop?
If your car stalls when you come to a stop, it could simply be a dirty air filter. The air filter may have become so clogged that not enough air can pass through it to the engine. An air starvation problem in your engine could also be caused by a mass airflow sensor.
Why do my rpms drop when I come to a stop?
This is a common sign of a dirty or failing idle air control valve. This is all controlled by the idle air control valve. When the engine RPM drops below the normal range of 750-800 RPM (for most cars), this often times will cause the engine to stall indicating a dirty or faulty idle air control valve.
What should the Revs be when stopped at a stop sign?
Started again, drove down the road, got to the stop sign, stalled again. Went away for a few days, came back, tried it again. Messy to start. Car hovers at 900rpm when idling and every 10-20 seconds the revs would slowly drop to about 500rpm before kicking back up to 1000 then back to 900.
When does a car stall at low rpm?
The RPM goes to 0 and the engine shuts off. This only happens when travelling at low speeds (e.g. slowly accelerating from a stop, braking, moving in stop and go traffic) This NEVER happens when I’m travelling above 10 mph (e.g. if I’m coasting at 40 and let my foot off the gas, the RPM can go to 500 RPM but it will never stall in this case).
What should the Revs be when idling a car?
Car hovers at 900rpm when idling and every 10-20 seconds the revs would slowly drop to about 500rpm before kicking back up to 1000 then back to 900. Every now and again it wouldn’t recover from the drop and would stall instead, several lights on the dashboard lit up telling me nothing.
Why do engine RPMs drop when coming to a stop?
Coming up to a stop and sometimes, not all the time, the cars rpms will drop from the normal idle of 650, down to less than 400 (?). Could be related to my P0420, but want to rule out everything I can.
