Check engine light's been on for 4 years
Looked at spark plugs location &
said no way!! I bought it from my
mom& she bought it used. I worked
auto auctions & hooked it up to the
computer analysis tool & it looked like it
was the check engine sensor, but it still
got good mileage then(2012) last road
trip from Washington state, pulling a u-
haul,to Amarillo in 2016, still good
mileage. Between March of' 16- now it
has plumetted. In this picture I can
identity everything except a black
rectangular box where the big air hose
bends under the tiny hose. For some
reason I believe that has something to
do with the problem as well as needing
a tune up.
