    So my car has been having problems today. At fist I thought it was the transmission was all messed up. Feels like it's slipping. Feels like it's stumbling on its self to. So it made me think transmission. But what's super weird. Is my exhaust is so quiet now. My cat back is no res and muffler that has a crack in it. So it's super loud. Well since this problem. It is so quite now. So I was thinking a clogged cat maybe?

    Have you noticed a significant loss of power?

    sounds like the cat, see if it glows red at night after driving it. or if the front manifold is glowing red, the cat is good and clogged.

    Sounds like when my comp g had a clogged cat. Had a hell of a time getting it to 60mph. Didn't really want to go over 4k rpms. It also was making 13psi on a stock pulley with an XPZ cam.

    Got it home. Hardly. It's so slow. About doesn't want to get to 3k. It sucks. I'm gonna sleep on it. And maybe pull it in to the shop at work and and get under it and put a hammer on it see if it gets louder

    Nope. It's been on ever since winter. Cause my coolant temp does get up to normal operating temp so it's always on. I'll scan it at work tomorrow. And maybe I'll have a new code
