THANKS GUYS FOR THE TIPS, THE CAR HAS 114,000 MILES ON IT, THE SENSOR IT SELF IS ALL GREEN FROM CORRISION, I TOOK THE MAF OFF AND IT WAS A LITTLE DIRTY BUT I JUST FIGUERED THAT WOULD BE FROM 114,000 MILES. THE DEALER IS A SUBARU DEALER I JUST DON'T THINK THEY WANT TO SEE ME CAR.

[Whats wrong with my XT6]

Ok I am in some real need of help, My xt6 just started running really poor and really really rich, this was about a week ago and i had it to my local dealer, they put a new cap and rotor, and some dry rotted vacum hoses on it. I got it back running about the same maybe a little bit better. I took it home and changed the plugs, the front 4 where fowl horribly. and the back two looked really good. i put another set in and got the same result. I would really hate to have to get rid of it. It was my first car. And its making a mess of my sti with the snow and all.
