Hello all,
I'm having some weird engine problems. 1991 Grand Marquis, 5.0L SO, AOD, etc.
At idle or low RPM, no matter what the gas is at, it will randomly cough, buck, and/or stall. Check Engine light flickers while it's doing it, but goes off afterwards.
We have replaced the idle sensors, spark plugs, distributor parts, alternator, battery, air filter and fuel filter(not all specifically related to this problem), and it's done nothing...the one thing that has made it run smoother and better was to clean the upper intake manifold with carb cleaner. Idle air sensor is cleaned and functional
Any ideas on what this could be, guys? It will even cough or stall with medium to full gas...I can't figure out what it is!
