2006 ford explorer p0191 intermittent stall

SOURCE: 98 Saturn SL2 - Stalling issues

I had a problem with starts on my 98 sc2, did it twice only, but it would start up, shake a bit then shut down like it wasn't getting fuel, or a wrong mixture. Replaced the coolant temperature sensor and starts / idles like new now... goodluck

SOURCE: Reduced power code comes up and my truck stalls.

I had the same problem, and the solution was cleaning the throttle body, it does need to be completely removed to be cleaned thoroughly. I just used some brake cleaner on a rag to clean off all the carbon deposits. A friend of mine who is a dealer tech had only seen this trouble code once, and this was the solution. So far, my light has not come back on and the truck is running alot better at idle.

check throttle body and pcv hoses and ports for blockage possible carbon build up and sticky iac valve

try the fuel filter

The code description is a giveaway.
It could be one of the coils on the coil pack. Most coils nowadays do two cylinders each. This way car makers can get away with one coil for two cylinders.(lowers costs) One spark fires the air fuel mix in one of the cylinders and the other will fire the cylinder on the exhaust stroke. If the coils are removable, and you are fairly handy with cars,switch two around, the problem will follow the bad coil.
