I have a 1999 V6 Cougar w/ a Weapon R intake. About a week ago my check engine light came on and 2 days ago i brought it to autozone and they said it was running rich. Im 16 so i dont wanna spend too much money fillin this thing w/ gas so i wanna know how i can fix this problem. Any fixing advise and maybe even a diagram on what i can do would surely help.

Yeah, i am having the same problem as well. I am going Friday to get a new exhaust system. I would say to get it checked out at a muffler and brake shop, they will tell you everything.

Ya, im not sure but i dont think its my exhaust. The last owner installed dual borla exhaust system and i think it was only like a year ago so i dont think that would be having problems already. But one time it like semi-snubbed on me, as i still had gas for about 10 extra seconds but the pwr steering went out right away. Now its all good yet but the light came on shortly after.

you might see if you have a bad O2 sensor i just replace one in my car and it was doing the same thing

so did ur car work fine after that, along w/ the checkengine light going off?

today i took out both of my o2 sensors and cleaned them kinda, nothing seemed wrong w/ them to the naked eye but im not sure, do u think that i should actually get them both replaced? because they are kinda expensive
