Having problems with your 1993 Mercury Villager ?

Engine first runs good, but progressive chug/misfire.

\015 The motor starts and runs well, but after several minutes begins to hesitate on acceleration with progressive chugging and misfire, loss of power, etc. Merely letting engine cool down a few hours is not enough to get clean engine start. It neeeds to sit over night I've done plugs, wires, rotor, distributer cap, ignition control module, Sea-foam internal wash with 2 follow-up oil changes, and catalytic converter. Still same problem. Check engine light works, but goes off upon starting engine and stays off indicating no apparent error codes being detected.\015 Posted / edited by AnonymousUser on : 19-03-2018

Answers :

Check for vaccum leak, if not check or replace mass air flow sencor.
The coil is most likely the problem. As it gets hot it will malfunction
