1998 Ranger XLT Sputtering/running rough at cold start

[TC10284]

I have a 1998 Ranger XLT with approx 195k miles that is sputtering/running rough at a cold start - typically when the truck has sat for a day or more. The longer it sits, the rougher it runs at a cold start.

Typically it will sputter and run rough for about 15 to 20 seconds, and then it runs normal with no issues. Sometimes it will cut off when it's bad, and I have to start the truck again, two or so times.

I've tried fuel injector cleaner and a new EGR valve with no change.

Could this be a bad sensor?

I had the same issue on my 04 3.0 and after trying everything anyone I know told me I found that the mass sensor had came unplugged plugged it back in no problems since
