    I got a 1990 F-250 with a 7.5l engine. I got this truck for my graduation present from my father a couple years ago. Ever since I've have it, he swears theres an o2 sensor that's bad and its died on me twice. The kicker is theres an after market exhaust on the truck and only had one o2 sensor between the catalytic converter and the engine. If anybody could let me know how many sensors this truck has and were they are supposed to wired it would really help me out alot!
