with my emission problems.. i was wondering.. i have a newer engine in the
car but all the exhaust/intake stuff is from the old car. that being said..
when the old engine let go, could it have fouled the 02 sensor? thusly
giving false readings, contributing to my emissions failure and causing the
21-23mpg i am getting right now?
