idle is feeling funny, not searching, surging, or any of those, just different from normal. Exhaust has new sound i have never heard of before, getting exhaust smell in the car. Also, every time i try to accelerate it seems to hesitate. Recent plugs, wires, maf, and clean iac. replaced O2 sensor due to 1151 code last week and code has not returned. I think the cats crapped because i have 180,000 miles and it did run lean for a while due to intake manifold gaskets. sorry to be so long winded, just seeing if i made a good decision to buy the cats without confirmation. opinions welcome.
