So this maybe (is :hick: :mullet: ) a dumb question but here we go. My 88 T-bird has the factory, 129,000 mile, 20 year old oxygen sensors on it. It's one of those things I forgot to change when I swapped in the HO and I just keep forgetting to get around to. Soooo how much is this costing me performance/gas mileage wise? I'm guessing I should probably change them :dunce:
When I run codes I get no lean or rich codes so I guess they are still working ok.......
the o2s sensors that oriellys and autozone kept telling me were the write ones are wrong so watch out. i would suggest taking your 02s up there with ya.
Performance wise ain't costing you anything... O2 sensors are ignored by the EEC at WOT...
As far as part throttle yes it's possible new sensors could give a bit better mileage and drivability, then maybe not...
Then I'll just replace them when ever I get the chance. ;)
get ford or bosch. i think thats who made alot of the
ford ones.they also come w/long harnesses for the
header h pipe--irv
i picked up 4 mpg when i changed mine
