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.
