Hello all,
I've been reading this board for a long time and this is my first posting. I have a 2001 4runner Limited 4X4, I added the supercharger and exhaust when the truck had only 500 miles. It now has 83,500. I just went through a "check engine" problem code 0171 and they cleaned the mass airflow sensor and then ran a smog test and it turned out there was a small vacuum hose leak behind the intake. The guy said when I re-oiled my K&N filter it messed up the MAFS but I have been doing that for what like 8 years and never had an issue before. Other than that my 4runner has been solid, no major issues other than routine maintenance although I know I'm in for a doozy at 90,000 miles. Something else interesting about my 4runner is that I'm still on my original brakes....3rd battery, 3rd set of tires, yet the original brakes.
