Hi Everyone,

I'm back on a stock rom to try and pass emission on my built Evo 9. I keep throwing 4 codes however.

P0300 - Misfire
P0172 - System Too Rich
P0069 - Manifold Absolute Pressure / Barometric Pressure Correlation
P0106 - Manifold Absolute Pressure / Barometric Pressure Circuit Range Performance Problem

I realized I had an Evo 8 MAP Sensor put on the car yesterday by accident and was wondering if you think this might be the issue. I found a single post on the forum which alluded to the fact that they are different, but can anyone confirm? (I know they are different part #)

Also, no matter what I do I can't get the EVAP to become ready.

Any ideas at all on any of these issues at all?

Thank in advance.

 

Why are you using an evo VIII map sensor on the IX? Were you using an omni bar or jdm map sensor then you switched back? if so did you remember to change your rom settings when you swapped it out?
