Dear gentlemen,
I've been fighting this battle for a while. The car is stalling at low speeds. This morning while driving on the highway we approached a traffic jam. When I reduced the speed, the car stalls when it reaches about 10 mph. It turns on immediately when I restart it. I notice that the voltage fluctuates before it dies. My mechanic recently replaced the crank position sensor because the car was not starting/rough start. Also recently, a Sears shop recently replaced the accessory and AC belt (the only two rubber belts). Thank your responses!

 

Mmmmm, a USA market car.

I would be getting the "idle control valve" looked at, they do carbon up.

The EGR (exhaust gas recirculator) system you have in your market, also reeks havoc with idle. I am of no help with that, we dont have that system.

The inside bore of the throttle body itself is prone to "black carbon goo" build up, which also causes idle issues. A simple wipe out with a solvent soaked rag (petrol if nothing else is available) will restore the throttle disc gap, and may sort the stalling.

 

I would check everything grant said, but it may also be ur throttle position sensor. I changed my egr iacv and even put a fresh tb only to determine in the end that the tps was defective. I would also check the mechanical screw on the side of the tb and do minor adjustments, that may work for you too. Also an engine setup may be needed.

 

Thank you for your advices. I'll take a look at both valves and report back....I cleaned the idle control valve and the car is working a lot better. No issues so far. Thanks!
