error code help
Helo

I have a 02 wrx. Monday it started running bad and pulled two codes.
P0102 and P0245. I replaced the maf sensor today but it now
idles rough and my boost spikes. I read about the 3 port solenoid but I
am clueless about what is wrong. The dealership said I would have to
buy a new turbo. I would love any suggestions or advice.
Thanks
Allison

Just checked the code again and only showing mass air flow sensor circuit low.
So odd.

Check the wiring? Apparently one of the wires has heavy shielding and needs to be properly shielded or you'll throw that code.

When its cold. As soon as it heats up it backfires
