Ok, well lately when I start warming up my car, it sound like if the exhaust is trying to get some stuff out of it. Dose that from time to time and sometimes it makes my Idel go and up. But once the car is warm is fine it stay at 1K. I drive it fine but then I am driving hard and start decelerating like around 70Mph or so there is time it will sound like it shot something out of my exhaust. LOL! I am hoping is fire but I know my cat is not punch yet.

Any idea why my car is doing that?

Is it time for an RB exhaust system? Sorry, I don't know much about a stock 12A.

if it sound slike a studer then that happens every time i let off my gas unless im going 30-40 in 2nd gear then let off the gas and BAAAMMMM loud backfire......i had to go threw a park zone and slow down so i down shifted to compression brake but ended up just leaving it in 2nd goin around that speed withteh rpm's at the mark and then i let off at the crossing with a little kid on his bike with training wheels bam that kid started crying...felt bad for a sec untill i shifted into 3rd and flew off

I dont think I've ever heard a rotary NOT backfire at some point or another.

They tend to backfire under engine braking/deceleration

my car used to backfire i TON then i changed my cracked intake manifold gasket and it made a big difference... now it only backfires when i lay off the throttle at about 7000 rpms

Thats funny there Rusty Shackleford, same thing happen to me sometimes out here in the quite area.

I hear ya Alak, I guess is just a rotary thing then. hehe

Dan_s_young that is sometimes were I hear it loud in the freeway is when I let go the throttle around 6-7rpms. hehe

Sounds like you got an exhaust leak somewhere.

Ya thats usually what makes it backfire. Too much air. Mine did it under hard deleceration normall, but onetime I removed my exhaust pipe to change a gasket and when I put it back on, I didn't tighten it all the way. It was like a Machine gun.
