I had these codes. I only get them with newer MHD maps that have had valvetronic adjustments done which twisted tuning never explained in any type of detail.
So i dont run these maps anymore because i personally believe there is an issue with them. Eventually you get these codes enough and your car one day will not start because the motor is out of limits. That happened to me.
I now run older rev maps that dont have any valvetronic adjustments messed with. And i never ever seen these codes again.
I was told i might have to change my motor. But i havent changed a thing but the map and everything has returned to normal for thousands of miles.
So just FYI. Not saying thats what is happening with your car could be different.
Also no this has nothing to do with PCV.. PCV noise is idle only.
PVC is a pipe plastic for plumbing LOL |
GREAT INFO!
How do i go about getting an older version of an mhd map? I run the up to date ones and would like to avoid any issues.
