Oxygen sensor

Oxygen sensor
Have a 1986 pickup with the '92 motor and it is only getting 11 miles to the gallon. I am curious to know if the oxygen sensor could be the main cause of that, Because my front oxygen sensor is rattling in place and my rear one is gone blocked off. I am wondering if that is what I should invest in ( cause oxygen sensors are kinda spendy) or start looking somewhere else

My 86 4Runner has 1 only, imagine trucks are the same.
If its loose then air is being registered that should not really be there and the computer might be richening the mixture thinking it is running lean.
Fix it and see what happens.

2) If the engine light is flickering, it's likely to be storing codes. Why don't you read them. Don't put too much faith in the code, though, since your loose O2 sensor is probably feeding wrong data to the ECM.

If you are only getting 11 MPG, then you will break even on having a muffler shop fix your problem in about half a tank. There really is no reason not to do it right.
