Missing O2 sensor?
Another newbie question to ask (referring to my earlier post of my engine not running properly):
whilst having a look under my truck, I just found out that it has no 02 sensor, and there seems to be no fitting in the exhaust. Also disconnected the air pump using a shorter belt. Found no trouble codes either on the computer. So could it really be that some of these trucks never had anything like a 02 sensor (has all the other emissions regulation stuff though).
