what happens when you ground the green plug located at the pressure sensor box aka boost sensor? is it also a diagnostic plug? and is there a relay to that or fuse?

 

pics would help..
Why did you ground it?
some background would be beneficial.. so would knowing what kind of car it's on.

 

that is if it is green and has 3 wires is how you adjust the TPS, just leave it alone

 

its on a s5 t2... i actually grounded it already before ... and i think i fucked something up... damn my car has so many weird things on it... i drove for a bit after i grounded it and then i boosted and then all my idiot lights lite up and my car stalled during boost.. maybe i overboosted and blew my engine? now the car takes forever to start and when it starts it keeps backfiring and the engine is super shaky... the idling is very messed up i think its misfiring or something...

so basically i was wondering if theres a way to sorta maybe fix it? otherwise i probably need a rebuild i thnk

 

is ti the green plug on the left of this pic?

 

correct the one that is attached to the pressure sensor on the right strut tower

 

i think you may have burned out the TPS, go to a junkyard and find one, they probably wont charge much, circled in red at center of pic,



do a search for TPS adjustment

 

Yeah, and after you replace the TPS, you should fabricate a heat shield box around your cone filter.
