Help!! I just seen my friends car and I noticed that his MAP sensor had a hose that runs from under the intake to the MAP sensor. My car dont have that hose. is this normal??

do all your stangs have that?

 

was your freinds car one that is speed density?

 

yes it is

 

thats why its connected

 

so my car is fine its normal the way it is.

 

yes, and if his was disconnected, it would be stuck in open loop and his injectors will be washing his cylinders...

 

you have "bap" and you have "map" sensors...manifold absolute pressure ,and bara-i spell it wrong absolute pressure..

 

cool thanks.
