If it is just stalling on idle and the bike rides and performs fine ie, not blowing any black smoke then all you have to do is turn the idle screw on the carburetor (phillips head screw with a spring behind it towards the top and middle of the carbie) in clockwise until the desired idle speed is reached. If the bike is blowing smoke or running roughly it my be necessary to adjust the fuel/air mixture. to do so turn the screw to the lower left side of the carbie in until it lightly seats, over tightening will damage the seat. then unscrew anti-clockwise 1 1/2 turns.
If this fails it may be necessary to pull apart the carbie and clean or replace the main jet.
Could be the Idle, or some kind of adjustment with the air and fuel mixture.
it may be as simple as a bad or weak battery of a bad idle air control motor
Well I am assuming that you car has a manual transmission, and it is stalling because you are not pushing in the clutch when you come to a stop. The more likely reason is because your idle is set to low on your car. Your most likely culprit is the carburetor. However if you car is fuel injection I would take it into a mechanic and get their opinion.
i had that problem with mine. the problem was an intake vaccuum leak. the engine wasnt getting enough air sucked in at idle and stalling out.
The Idle speed control serves a few functions such as increasing the idle when the vehicle is cold to keep it from stalling. It also responds to increased engine load such as when you turn on the air conditioning or turn the steering wheel at idle. Without the idle speed solenoid the vehicle would stall nearly every time you came to a stop.
Check the idle, if its fluctuating or falling than nomal. Usually, low idle causes stalling when coming into stops. Low idle, usually is due to dirty throttle, a leak in the vac hose, or a damaged MAF or IAC motor.
I think I understand what you are saying. If your car is stalling and you want to figure out how to get that to quit, have the idle and throttle checked out. Idle might be set to high. Also, the throttle body might need to be cleaned. A great website to figure out how to do this is at www.trustmymechanic.com
Replace the Idle Air Control Valve only about $50. This would cause funny idling and stalling out.
try replacing the throttle positioning sensor AND the low idle air sensor
No. Most likely you have a bad IAC (Idle Air Control) on top of the throttle body. A vacuum leak would also cause stalling at a stop light. The IAC looks like a small electric motor held down by 2 bolts that take and 8mm wrench.
Use the clutch.
Possible causes, idle air control valve, dirty throttle body, egr valve clogged, major vacuum leak, maf dirty, intake restriction.
