Stalling in front of traffic light / idling speed / braking
My car is running nice and smooth at most of the moment, no miss, no ping and not even any excessive noise. However, I've got a random stalling problem this few weeks, after I've worked on my radiator (flushed, replaced new side tanks, new thermostat). It only happens when your foot is off the gas pedal, but not always, may be 1 per 100 times. The stalling can happen at anytime no matter the engine is warm or cold, if it wanna stall, it simply stalls. However, you can always start the car immediately after the stalling. Other than that, the car is running nice and smoothly.
Here is what I've done so far:
1. New Batteries
2. New Alternator
3. New Plugs
4. Oil Changed
And here is what I'm suspecting:
1. Dirty Fuel Filter? (But how come I don't get stall when I rev the engine up?)
2. Distributor Cap?
3. Spark Plug Cables?
4. Airlock in Fuel? (But how come it will happen in a cold night)
5. Faulty Fuel Pump?
6. Idle Speed Motor?
Your input is much appreciated. Thanks in advance.
Swift. Agile. Deadly.
