P0300 Code after Cosworth Cam install
So I have a P0300 misfire code and a Second O2 no activity code after a Blouch Turbo and Cosworth cam install. I have Stage 3 upgrades, NGR test pipe, with AEM intake.
I was reading through the Evo X service manual and it looks like they really stress looking at the camshaft position sensor.
So question:
1. So my tuner says its impossible to not have a P300 code after a cam install, is that true?
2. Anyone else have the P0300 misfire code after cam install?
3. I take it the second O2 sensor low activity code has nothing to do with the misfire? Thanks!
EDITED: I just realized I posted in wrong section lol.

Most aftermarket cams throw Misfire and most if not all tuners disable it.

was about to say turn off or rather delete it out the ecu problem solved no light but if you need it to pass inspection your screwed if you live in one of those aggressive states.
