So i have to drive up to wisconsin with the lady this weekend . I have a check engine light on. The codes are the P0401 code (comes up twice) and a bad Bank 2 O2 sensor.
I cleaned out the EGR today with brake cleaner. Replaced the gasket due to it being cracked. Cleared the code and have not driven it to see if it comes back on. I believe the next step is VSV. (Looking for a write up on how to replace that)
In the sense of doing some cleaning up, I cleaned out my throttle body with cleaner. Recharged my K&N and cleaned out my air box.
About a week ago i got my trans fluid changed and oil.
I'm in this upkeeping mood and looking for more things to do to improve MPG and get some better pick up on the car.
This may be a FAQ but it's an update on the ole girl.
Let me know if you guys have any input. Thanks !
