Stumped

How about clogged injectors? My 4.0 sat out of the truck for some time before I got it and dropped into my bronco, started off running only on 3 cyl, then one by one over a few days of starting and letting it idle the other 3 cyl got in the game.

Just an Idea

Fellas, finally found the problem ... The MAP sensor was bad! Had a guy hook up a scanner and it coded out the Manifold Air Pressure sensor. After 10 Months, six mechanics, numerous parts swapping and internet research, I'm rolling again like a kid with a new toy.

Thanks
