Very Weird Problem

[1999Powerstroke]

headin to work yesterday and left the house and she wouldn't get past 31 mph, just flat out had her floored and that was all she had....it wasn't like she was trying to die, she ran fine, loud and strong, just wouldn't go past that point...up shifted to nuetral and back to drive and nothing changed...almost like bumping the governor on a semi....pulled over, shut her off, started her back up and she immediately ran just fine, no problems at all and she's been fine since!

please help...what could it have been?

was it cold out when you first started? the exhaust has a thing that closes and keeps the exhaust in the engine to warm it up. maybe that was stuck for some reason.

it was about +15 degrees and the truck was warmed up good....it's definitely been colder...could this have anything to do with the injectors or needing a wicked wheel?

thanks!

nope u dont need a wicked wheel at all.

And it has to be the exhaust valve otherwise it wouldnt have just went away.
