2002 Mercury GM LS

When ever it rains or heavy moisture in the air the car stalls at every light. starts right up, but dangerous when it stalls going slow. Never happens in dry weather?
Any idea why? IAC ? 2002 Mercury GM LS

Wouldn't hurt to get the codes read to see if there's any clues. IAC might be one possibility. Does it sound like it's just idling really low or is there some hint of a misfire?

Has it ever been tuned up or had the ignition wires replaced? You might start it up in the dark and see if there is a light show under the hood.

Moisture, moisture, and moisture collecting somewhere!!! Should it have been a dizzied engine, dizzy cap is culprit number one. It's solid ignition packs, right? Or, maybe, you are lucky and it IS distributor, so then you know what to do. New cap and rotor and gasket/O-ring.

No misfire. idle slows and stops. Only when heavy moisture around. Once engine gets hot problem stops. Coil on Plug. No typical ignition wires.? I just pulled all of the (16) connectors to the Coils and put dielectric grease on the pins, try that , next rain Friday.

Any idea where the rear Air Suspension valves are? Is it a Do-it-yourself fix?
