H/C install / Dyno Tune--P300 code Why?
Had a H/C package installed recently and the car Dyno tuned. Runs great but P300 Code continues to pop up from time to time. What does this mean?

random misfire detection.. if you have access to edit, you can also adjust the idle and low rpm tables to 32000 to help with the problem. PCM's don't deal well with lumpy cams. This is all assuming that you don't really have a real misfire of course..

What are the specs on your cam?
I was getting the a misfire code also after I changed my cam but all I did was enrichen my a/f at idle and it took care of it.
