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.
Check for vaccum leak, if not check or replace mass air flow sencor.
If it helped , glad I could

The coil is most likely the problem. As it gets hot it will malfunction
Is your engine a v-6 3.8 liter?i had similar problem with my ford,found it was pick-up coil in my distributor,nationally known auto repair told me it was 8 different devices with their $1300.00 analyzer. pure b.s.

Thank you. I've been following advice of well meaning "motorhead" friends only to get more frustrated and discouraged. I just can't afford to dump "shop rate" labor into this vehicle. You give me hope I'll be able to winter with it another season.
