Man, what is it with Q31. I had mine burn out as well on two diff. P28's. Im pretty sure it has to do with the O2 heater. I havent looked into what the exact part is, but I bet you could find out on PGMFI.org.

yeah, i've seen a few, and from what i hear, they burn up like that from people switching the purge evap solenoid plug with the iat plug (similar plug style). there's been three 4 of these posts in the past month anyways, it's not needed and the ecu will function proplerly without replacing it, but like xenocron said, it is part number 2sd21780 from digikey
