Take the O2 out and check. It it has oil on it then clean it and try to see if it help. Oh and it would had been easier if it was on one post.

 

yea it was an after through t lol i have problems when i put to many questions in one thread not many people seem to want help out as much

 

Best way to tune a car with problems - make them fix the problems first. You shouldn't boost unless everything works 100%. Unless you have a DSM, as that's impossible.

Depending on how the O2 is mounted, it can be clogged with burnt oil residue. Since the sensors are very sensitive, it could cause an issue.
