ok, my problem.. i just put a rebuilt F23 in my car. it started, but it does not run fine. when it's cold, for about the first 30-45 secs. it runs ok. then the idle flucuates from 1k to 2k around that area. when i give it gas, it bogs down, but when i let off the gas it goes up go like 4k, as it should do while i'm giving it gas. if i stay on the gas it'll stall. it's shooting codes P0301, 0302, 0303, and P1399 (which i'm not sure about that one)... i've checked the IAT sensor, the TPS sensor, the knock sensor, all four injectors, and they're all good. my buddy told me it sounds like the timing is off - I've since re-timed it about 13 times, but it's not getting any better or worse. they're aren't any vacuum hoses leaking, and every once in a while it'll backfire a little. there's no exhaust comin out the intake, but it seems like the exhaust comin from the tailpipe is intermittent.. that is, it kinda shoots out bursts. please help, i've been w/out my car for way too long and i'm so close to the end lol. thanks.
