My car is stalling intermittently, what could cause that?

Diagnosing an intermittent stalling problem can be a challenge, especially if the engine is only stalling occasionally (which never seems to be when you’re at the workshop). The best thing to do is to take your car  to your local workshop, they will put a scan tool on your car to see whether there are any pending codes, hard codes or history codes in the vehicle’s computer. Be prepared to leave your car at the workshop for a day or two, it is difficult to diagnose a fault when the issue doesn’t happen all the time.

Every engine needs three things to run and idle smoothly without stalling: a correct air/fuel ratio, sufficient idle speed for the idle load, and a good spark. If any of these is lacking, the engine may stall. Cold stalling problems are the most common because the engine needs a richer fuel mixture to maintain idle speed until it warms up. Intermittent cold stalling problems are almost always fuel-related.
