I have an 04 sti, just rebuilt the motor, started it today and it will not idle. If I keep it idling it runs rough and will backfire when the rpm's get below 1000. The engine was rebuilt to all stock specs. I have a DP and turbo intake pipe otherwise everything else on the car is stock. I am new to subis, but have worked on dsm's for years. The cel has not come on, but I only had the car running for a few minutes. Any input will help .
It's going to sound like hell on your first start up. I cringed when I first started mine up, it sounded terrible. We let it run long enough to get warmed up, then I took it out for a drive, and kept it around 2k. It should smooth out.

I am almost certain the timing belt is on right, I printed a thread on how to replace a timing belt and everything went very well. Also when I keep it at a low idle is sounds like there is a boost/ vac leak near the turbo inlet, but when I raise the rpms it seems to go away. Not to sure about this going to look into it tonight. Thanks
