Its a inertia problem. Its a known problem with lightweight flywheels.... The flywheel drops speed faster then the oem because of the weight differance. There is not enough mass to keep the engine stable just off idle.
The engine then uses fuel to try and adjust for it.
Then it cant keep a steady idle you get a misfire code. DONT DISABLE MISSFIRE CODES!!!
Go into the rom and adjust the right table. (requested torque) off top of my head. Raise it few % from 800 rpm up to 2600. ADJUST ROM AT OWN RISK. Take to a Tuner as results may vary.... read up on it a www.romraider.com But I recomend Crawford Performance. They can tune over the internet. Call and talk with LIC Motorsports about getting a Crawford tune.

I have a lightened flywheel, and I'm getting these codes too. Though mine is multiple misfires(p0300), cyl 1(p0301), and cyl 4(p0304). Should this still be happening with my cobb stage 2 tune. I have an spt intake, catless up and down pipe, and catback. If I throw a code while having the car tuned, is it normal or do I actually have something wrong. The car drives fine, now that I changed the plugs yesterday and pulled the neg side off the battery. Everything was fin until today, when I randomly turned on again. It's sickening! It makes me hat the car, then I drive my 96 civic for a while and when I get back in I just deal with the cel and love the car.

Even with a tune, has anyone still gotten smoke out the exhaust. I get a bunch of smoke that comes out like every other startup while sitting at a light or in traffic. Just waiting to get a ticket for that.

Pull your intercooler. check to see if you've got excessive oil in it. you can also take your exhaust manifold off and look for wetness and heavy carbon build up. That's tell you if its isolated to a particular cylinder or if you've got excessive crankcase pressure or a leak in your turbo. The age and mileage with a stage 2 tune. I'll tell ya dude, that motors coming out. DO NOT use any fuel system cleaner or Seafoam. All that carbon build up will break of and imbed into your ring lands. It'll just ish worse.

Any of the shops will be able to help you with this. I just layed out GST cause IMA fanboy. Is one better than the next I dunno. I'd bet a pitcher that every shop in the area has performed work on a car that was serviced at another shop. SOme do have better reps than others. Some do certainly take care better than others. GST for example, their "secretary" gives superb reach arounds.
