Got this p28 from a buddy of mine.. and its damaged - you can see some burn marks on the board and whatever the little pice sticking up is is fried.

Is it salvagable? TIA

 

Yep, it's salvageable. $20 plus shipping is my going rate.

 

just take q31 out they alwayz burn up for some reason like p72 and p28's just move it back and fourth until it brakes loose you shouldnt have any props/
and im speaking from experience.

 

Its fine, looks like someone crossed iat with egr.

q31 is the burn piece?. If so, cool deal. Ill do it. If I do break it off, will it present problems with things like the IAT?

EVAP Purge solenoid, not EGR.

They only burn out when the IAT and EVAP Purge connectors are swapped.

If your state has strict emissions standards, you may need Q31 functional. If not, you should be fine.

 

are you sure, every car ive ever put a p28 with q31 runs fine for like 5 seconds and then bam burns rite up, are you sure its iat?

 

q31 is for the evap,

after you take that out, do you still have a check engine light?

If you have the EVAP and IAT plugs swapped, yes. You most likely have melted your IAT sensor and need a new one if that is what happened.
