o2's

So I just put in 2 brand new o2 sensors in my longtubes. So going from no sensors to this, should i be expecting anything?

what did you buy oxygen sensors for? and what do you mean having no sensors?

Well ever since i first put in my MAC longtubes back in June, i have not had any o2 sensors in. Then i heard not having any in would cause the car to run too lean and run in an open loop all the time, so i went out and bought 2 bosch ones for up front to put in the long tubes.

what! you had no sensors this whole time. well glad you got some in there now

yeah i didnt have any sensors. So having those two up front, should i be expecting anything?

yup, better fuel mpg, cause now it won't run in open loop

i guess what i am asking is... how do i know they are working... because i have a lot of electircal issues that i wouldnt know whether or not the sensors are working or not

run a koer test and if no o2 codes come back they should be working, or back probe the 02 on the right wire and watch the voltage range

im guessing i need a special device for this?

No. Volt meter. .5 volts is 14.7:1 Above .5 is rich below is lean. But they Have to be warm before u can trust they readings

so then whats the procedure on doing this?

google "diy koer" Ryan look for a link by joel5.0 koer can be done with a simple paper clip, once the test is run it'll spit out any systems that are malfunctioning in the efi system

Ahhh i know what you mean. Same thinkg with GM OBD1. Flashs the MIL in sequence and you referance the maneul to find out what codes you got pretty much. Nice. Didnt know Ford had something like that.

yeah, ill be checking this out my first day of break... so in 17 days :p
