Cuz ive been getting this p0300 code for over a year now and i just recently found out it was coding for the p0401 also. Could it be the cause??

Not necessarily. One of your hoses popped off of your EGR. Check behind/under the intake manifold and you'll see 2 hoses. You can use some zipties to get them snug.

For the P0300s - go to your local tuner and have them disable it. I've had no codes since...

 

How do you disable it??

 

A pro tuner will know how to disable it. Or you can search the forums. 0300 is a known bug for evo 8s

 

Well i have searched on how to get rid of it and most people say to goto the dealership to get a reflash, but then ill lose my current tune. Can anyone offer me a link as to how to disable it?

ive had the P0401 and P0300 code for a while now. i havent searched the topic well enough yet but after reading this thread, i hope it solution isn't getting it re-tuned and losing current tune

 

The dealer reflash may have fixed a few car's P0300 code but for most cars it did nothing. In other words, not a good choice.

The real fix is to have a tuner turn it off. They can do this without touching any of the rest of your tune.
