Most times when I start my car in the morning or just after it's been sitting for awhile the exhaust backfires A LOT. It almost sounds like it's cammed but speed up. The muffler shakes around during so too. The car has headers, and exhaust and stuff, and it normally backfires a little at idle, but only a little. It's constant backfiring and sounds like something is wrong. Just today I started my car up and it did it again, immediately drove, and at about 4 grand it went crazy and backfired for like 4 seconds (keep in mind I was accelerating, or trying to) and the tach just bounced around 4. After the car warms up the problem is gone. Car is a 99 dx with a D16Y7. Thanks

I don't think it has to do with my IACV.. It sounds as if the problem is in the motor as in the way it idles. I will post a video to show you guys.

Yes that is what I'm going to do. I just sure hope that's not what it is.
