O2 sensors

ninetyfivegtstang · May 24, 2008

Ok, my question is when do you know when the o2 sensors are out I just put in a new motor. Don't really know if I am getting bad mileage yet cause of new setup.

i just changed mine out.hoping for better fuel mileage.mine wasnt idleing good it would surge alittle,and it would stall sometimes i was told to change iac,and tps.i did a year ago it always did that until i changed my o2 sensors man i couldnt believe the difference it was throwing a code for about a month but even before it started with the check engine light it still would stall and idle rough.but all better now.baby runs smooth.good luck

I'm thinking I may want to put some new ones in mine before I try and take it through emissions. I know the bosch ones are total ass so what is a good replacement sensor to buy that doesn't cost like $80 for each?

The OEM Ford ones are the only ones worth the $$.

Well, drove the car today, mileage was actually comparable to what the car got before I did the HCI so maybe mine are still ok?

Motorcraft uses Bosch for their o2 sensors. my car was running very rough, misfiring, would run at what seemed like
20% of it's ability, and then BAM all of a sudden 100%... ran the OBD1 scanner and it said "bank 2 reading rich".
replaced both o2 sensors with OEM ford (bosch) and it runs like a champ now..

My O2s were causing idle surge and stalling. They did this long before causing Lean codes. I bought Denso sensors from Jegs for about $46 each. They work great.
