As it states, new engine fired up and seems to be ok. To refresh, im running an old tune with a new cam. When we first fired it up, the engine light came on and threw the code p0300. After checking, we found the brake booster hose had come off somehow and we put it back on. i erased code and have driven it 50 miles or so without the light coming back on. Could this have come on because the computer doesnt recognize the new cam, ported heads? Or because that booster line came off? Either way, it starts and runs fine. It idles up and down a little when in park, or when im stopped, but im guessing that this is because of the old tune/new cam deal. I left the 3.8 pulley on it until i get it broke in. I know what the p0300 code is, just wondering if the aforementioned issues could trigger such a code. It also threw an oxygen sensor code too, and I know this can cause idle rev issues. Thanks,
Kevin
