Anybody else experience a drastic decline in pefrormance with a bad o2 sensor. Mine threw a cel and the car is slower.

also what is the cheapest place online i can find a front o2 sensor?

yeah, performance will go down b/c you could be running rich/lean, and the whole a/f ratio gets thrown off b/c the O2 sensors are not sending the right signals!...

this is not the one you need, but i'm pretty sure this is the guy who can get you any O2 sensor for $70....ask, and if you get it, it's a steal

I wish i could remember but i dont. Its bound to get thrown anytime again so ill write it down.

I have a 95 turbo, so my codes won't apply with you, i wish i could help with that!

If you throw a P0133, you need a new front O2. I just had to deal with this myself. I bought my sensor through oxygensensorwholesale.com, and I got the "generic" one (it's not Bosch, i forget the name), paid ~$138. The sensor that arrived was Bosch so... I recommend them. Cheap and super fast.

(edit: oh yea.. clear that CEL/ check the code. If your car acts normal again for a short time after, it's the fO2).

DiscountOxygenSensors.com for a Bosch with connectors it was $136 for everything for a '94 850 Turbo for the o2 sensor before the Cat.. I would be careful with the guy selling them on Ebay if I were you because he did not want to tell me the part number. I did alot of checking and this was the cheapest I could find a Bosch with the connector on it for what is suppose to be the right part # . I bought this from this Co. just a week ago and all seems to be fine.

This company sent it right out to me, even overnighted it UPS for free for the price I stated above. I didnt even need it sent overnight but it was great.

If you have any questions about your O2 sensor just call their 800 number.

I've been pulling 4-3-3's, 4-4-3's as well as 4-3-5's and the performance of my '94 855T has really gone downhill. I used to get a nice amount of boost in all gears but as of late only after I get to about 50mph do I get to 3/4th's of the white. In first and second, I'll barely crack into the white even under WOT. All my vacuum lines are new including plugs/rotor/cap/k&n panel/tranny flush. I just installed a new universal front O2 sensor today, unplugged the battery for an adaptive reset and drove off expecting to burn rubber like I used to.

Nope. Car feels a little stronger, but still cannot get much past 1/8th of an inch into the white upon leaving the line. What gives? Please help! My girlfriend's fourteen year old pomeranian is faster off the line than my car at the moment. What else should I check for?
