O2 sensors?

My car has long tubs and I can't find the sensors I'm guessing they took them off and never replaced them is there a way to replace them myself?

Just like any other... Did you get under and look where you might could replace them? How did they not replace them? Are you not running a check engine light? I wonder if maybe they got turned off at one time I don't know??? All I know is mine won't run without them... Where's them o2 bung man them long tubes gotta have em?

If your car does not have them, that explains why your buddy outruns you.

The ECU cannot keep your A/F ratio correct without them.
I'd say you need to get under the car and find out for sure if they are missing or not.

Check engine light blinks. Or flashes?

2" to 6" forward from the end of the header collector, at one of the angles shown in the picture below.
