Hi Eric, love your show, keep up the good work!
99 Acura TL here (I know, I know, didn’t do my homework before getting the car). Been getting the dreaded P0401 code and have been trying to clean it three times. Recently was talking to a mechanic and he mentioned there was a fix where the EGR port is widen so a sleeve can be inserted. Do you know how what size drill bit and how far to drill?
Thanks!
