Wish I had an answer. I too have been protuned and the PO300 pops up from time to time. Sometimes it just clears itself, other times I have to reflash...basically no rhyme or reason to it. For me it tends to happen when I'm cruising at highway speeds.

raiceboi697,

I'm assuming your vehicle is a 2003 Evo?

Thank you,
Rob

rob,

close i got a 2004. im also one of the lucky folks who get this phantom code. the only other solution i have heard is if i get a COP ignition system it will go away, but a grand for a possible solution is a bit steep.

Can you email me your map that should have the P0300 DTC disabled?

Thanks,

You certainly can, but I would ask that you wait until raiceboi697 reports back.

Thanks,

Looks like something is amiss with the 2003-2004 misfire codes. I'll have to take a look.

Thanks guys,
