Exhaust leak causing problems?

Post by BobbyMang »

Hey all,

I got my car inspected yesterday and my mechanic said the only issue I have is a small leak due to a bad gasket in between the cat and the front muffler. I have a 2000 S80 T6 and I've also been experiencing symptoms that correlate to a bad ETM or MAF. i.e. some surging, bad idle at times, and hesitation while accelerating from a stop. I was just wondering if you guys think this leak could be the root of my problem, as I've ruled out the ETM as the issue and I've checked for vacuum leaks already. The leak is before the rear O2 sensor so this sparked a thought that it could be my issue. Let me know what you guys think!
