Hello all,

Recently picked up a 03 evo 8, and I am moving from dsmtuners.com to here.

looks like a great forum, and i cant wait to be an active participant,... well, have yoju guys fix my problems for me, in other words, haha.

I was registering, and somone had taken my username, i have always used, and I was so pissed off, but then i realized it was me like 4 years ago lol.

anyways, first post, and a first problem:

Car was throwing the Upstream 02 sensor, so i picked up a new one, and installed it, and for the cel was gone, for about 2 hours, then it came back. I am on my way to get the code read again, to see if it ate the 02 sensor, hopefully not.

just wondering if anyone else had a similiar situation.
Ill update when i know more,

Thanks,
adam

Do you have an aftermarket exhaust, down pipe, etc..?

 

Car is100% stock.

It threw the code for 02 sensor, so i replaced it, and now it threw this code.

after searching and chatting it up with other members on aol, we seem to think its a boost leak.

the car isnt reaching near 19 psi. a little under.
