About a year or so now. Put the catch can on passenger side as it’s the dirtiest. Cleaned all three MAP sensors and Thts it. I do my own full synthetic oil changes every 5000-7500 miles, check the can 2x between oil changes and check the sensors. The IAT Sensor on the intake tube and the TB sensor have never needed cleaning. The manifold sensor gets the dirtiest without a catch canplati did how ling have you had the catchcan on there. did you do any cleaning other than the sensors?
