my o2 sensor is bad can i use a bosch universal one?
 

could i use it and just splice and solder and heatshrink to the old o2 connector to save some money ?

depends which one you are talking about...the rear O2 is a relatively common narrow band sensor..and you could source something that would work.

The front WBO2 sensor is much different. I reads current as an output instead of voltage...not a common thing. You would be much better buying a new OEM sensor. After all...it makes the car run correctly in about 80% of day to day driving

thank you yes it is the front sensor the reason i wanted to save some money i have to buy more sensors because the cat somehow heated up and melted anything near it maibe you can help were to get the vss,solenoid valve,tr sensor,turbine sensor im looking for all those they go on the transmission. ive found this site is theis the best place and cheapest to get sensors or is there a place i can get these sensors used?

Might want to buy a used auto tranny..that might be cheaper than all those sensors :(

Try a wrecking yard or Mazmart as well....

thanks man i checked mazmart they dont have it but i think i am going to get a used tranny and use just the sensors and sell it without sensors to someone who needs the tranny it self. great advice and
it will save me time and money. do you recommend getting a used o2 sensor?
thanks for all your help

Personally...I'd get a new one....Paul had good pricing on them at Mazmart I think last time I ordered one...
