92 Mercury Sable 3.8 liter wont idle. Its stalls until warm - Ford Forums

My 92 Mercury sable 3.8 liter wont stay idling when it is first
started. I replaced the cap and rotor, new wires, and plugs. After it
warms up it usually will stay running but sometimes stalls at a stop.
Any advice.

Start by cleaning the throttle body and IAC. The IAC should
be removed and maybe soaked in solvent for a while to free
it up. Soak only the valve end - not the motor end. If the
IAC is really bad, it may require replacement to return to
normal operation.
