i need to buy some 02 sensors but there are two different ones and im not sure which ones to go with. i was looking at this to try and figure it out...

but im not sure what to get.... my car is 87 GT converted to mass air with A9P computer. also confused as to why they have two different O2 sensors for the 1990 year?

should i go with DY605 or DY606??

MIL eliminators are to take away the check engine light if you have no cats...they arent a replacement for 02 sensors im pretty sure.....

also they are for SN95 cars... i have a fox

Nope,

MIL eliminators are used on SN95/mod motor cars. The eec-iv in fox cars needs the O2's to function properly. I might have some bosch sensors laying around.

ah, gotcha. i know they aren't a replacement but they give signal to computer that O2 is reading correct (eliminating the cel)? shoulda figured they were only obdII compliant. meh, i run a carb and 3 ways underneath w/o air

I'm gonna guess and say they look different but are still 3 wire sensors.Ford used to use ones that were real skinny like pencils and then went to fatter ones like the Bosch ones you get at autozone.Just go to autozone or advance and pick up a couple bosch ones and you'll be fine
