P0300 Missfire FIX !!

p0300 misfire compadres: take a survey

Theres a few links to take a look at. This one has been covered for quite a few years now. Its a common problem on the Evo and can be turned off via the ECU periphery bits.

You need a tactrix cable though. You could just ask your tuner to do it too.

This is assuming by code 300 you meant p0300 as there is no "code 300"

Hope this helps. A quick search would have came back with a wealth of information.

EDIT: you have all of those mods and no tune? Looks like your running an FP white too. Maybe you just didnt list your tune as a mod? If so contact your tuner. Its a 2 seconds job that should have already been taken care of.

 

your best bet it to get a tuner it could off that code if it not something important

 

thank ethan for doing the searching for you

this issue has been discussed to deathhhhhhhhhhhhhh
