I used some universal sensors on a '96 Contour. I didn't solder the wires I just used heat shrink butt connectors and haven't had any problems with them. Check eBay for the sensors. I Was looking the other day and some people were selling 4 wire sensors for $20. each. I don't know whether they had any 2 wire sensors or not, but if they do it will save you a good bid of money.
how is your FE specifically? you haven't added to your gas log.
im getting around 21- 23 mpg.i just didnt want to post it up because its kinda low, and seattle had a few big snow storms where my mpg dropped all the way down to 16 mpg. im just so used to getting 46 mpg on my old civic dx.
does anyone know where can i find a cheap o2 sensor online or ebay? i saw one thats for a corolla, but its range is from 88 - 95, 2 wire, cost 25 bucks. mines is a 2 wire and the ones i find is about 50 bucks or more
