started getting a p0300 code after cam swap, assumed it had to be tuned out. well the tuner said the tables for it are maxed out, and the p0300 keeps coming back, said its not in the tune, but something else. possible intake manifold gaskets? well itsometimes runs rough now, like its not getting fuel. hesitating and almost stalling, but then itll be fine. other day I took it out and it idles fine, but the second I hit the gas it would basically almost stall and not rev at all. did it like 10 times, then it finally stalled. started the car back up and it ran fine. felt like the fuel pump was off. I took a video.
in the video when you see the idle drop thats when im hitting the gas. when i let off if would idle normally. any ideas? also could the p0300 be intake gaskets? cause if I pull the intake im gunna do a fast and rails and stuff all in one shot.
