We kinda need more info to help you figure it out. Is it causing an issue or are you just curious? Also where is it located in the engine compartment?

Buy a can of carb cleaner and spray around to see if rpm rise. It sounds like u have a vacuum leak and judging by the pic of the evap sensor u probably changed those vacuum lines by now.....hopefully

Also these cars have a bad case breaking the plenum gaskets btw

I have a dumb question check all the injector connectors being connectwd and very important there is a ground that goes to the valve cover which is a ground to the injectors.

Re: vacuum questions. guess

The top pic is the DPFE (differential pressure) which controls
Egr pressure. Google dpfe ford mustang for more info.
The second is is your oil pressure sensor. Make sure it's on.

Oops sorry. Looked at lower pic more closely. NOT oil pressure sensor. Btw, 1AA auto has explanation of egr and dpfe purpose and problems and how signalsfrom sensor go to computer and affect perf.

My dear friend im sorry to say but you are dead wrong on the description of the two pics. The first is his evap purge sensor and the second is the pic of his plenum from the back showing the vacuums that goes from the plenum to the sensor which is located on the passenger side near the a/c accumulator. Dpfe is a silver box with 2 vacuums which go to the egr tube if this were it it would be on the driver side of the firewall ill includes pics in a sec

Check this ground that goes to the injectors. As to testing them turn the car on. Then unplug each one on by one taking notice in rpm drops if any also by any chance would u happen to have the mil code that are on ir car. Im sure ur check engine light is on so knowing the codes would help alot to figure out wats happening
