When I drive my truck home from work (mostly up hill) I get the check engine light at a certain spot and it stays on until I get home. When I start my truck it is never on but it has been coming on on the way home the last couple of days and I always notice at the same spot on the drive home.

95 150 5.0 4x4

all my idiot gauges are in the norm, truck leaks a tad of oil, thats it

any ideas

 

o2 takes about ten min or so to set a code when goin bad

 

First thing I would do is check the codes. Then post back with what it says. https://www.ford-trucks.com/lc/lc.ph...om%2F%3Fp%3D13
