Hey guys. So I started my car yesterday (06 STi) for the first time since my rebuild. It has a new stock bottom end, the heads were rebuilt with light port and polishing with new valves and guids, and I do have mods including a CAI, Invidia N1 turbo back exhaust, bigger top mount, I have stock injectors but pretty sure they're modified. Anyway I start the car, it's misfiring, will not hold a steady idle, and the check engine light came on and the cruise control is flashing. Im pulling the code once my friend gets here with his scanner and hoping that leads to something but Im sure its just going to tell me misfire in one or more of the cylinders. I did put new spark plugs in and they are one step colder plugs. Not sure if maybe that has anything to do with it. Any feedback would help!
