Service Engine Soon: Grand Prix GT 3800: P0102 & P1133

I have noticed the engine sound "louder" or perhaps the sound coming out of the muffler sounds "rougher" than usual. So I don;t know if any of that is relevant. The car has 227,000 miles.

exhaust is probably rotting out on you. but the codes you have could make the car run poorly as well.

used maf's are like 40 bucks or less at a junk yard, the o2 cost around 30 to 40 new. if a pig tail has gone bad, they cost about 10 bucks new.

all easy stuff that should be addressed.
