1988 Bronco 2 To much Fuel

[Lynch51291]

Hey New here. Hope i'm in the right category.

Replaced my Driver side head due to a Burnt valve(I purchased it that way not knowing) Drove it for a couple months then i decided to pull it apart new gaskets
new head. It has alot more power. I also replaced my M.A.P Sensor it was bad but now when i leave the Vacuum line connected it revs up to 2,200 RPMs, When I remove the line it drops to normal RPMs 1,000 but it has a Studder and black smoke comes out of my exhaust.


Its a 1988 Ford Bronco 2 4wd. Fuel injected with the 2.9L Automatic

Are you 100% sure you have the right sensor in there?

The Right M.A.P Sensor? It was identical to the one i pulled off.

Can a o2 Sensor throw the Idle off? I have no vaccum leaks from what i can tell.
