I just put a 96 b18 ls in a 93 cx car starts/runs great it just wont idle. the car is giving me a code #1 O2 sensor but i dont think thats the problem. i checked for any possible vacuum leaks and cant find any,tried unplugging the iacv and it lets it drop a little set screw in T/B turned all the way in.

The 02 sensor is a four wire and i checked all the wires and they are ok is there a way to get a new/newer one w/out paying $200.00

 

take your IACV off and spray it out with carb cleaner, sometimes the valve sticks after sitting for a while.

and check autozone for an o2 sensor, it shouldnt be that much...

 

Thanks i will give it a try!

the 02 sensor is $150.oo for a universal and $200.00 for a oem from autozone i will look around and see what they are going for elsewhere!

 

get a universal that will thread into the bung on your header, one with a plug already attached will cost alot more. just a universal type you have to cut and solder the wires, but it is 50% cheaper.

 

i got one for $80 at the autozone by me, no cutting or soldering of wires needed...

 

for the o2 sensor go to the auto parts store find a 4 wire o2 sensor for a gm vehicle cut the plug off and solder it up...got mine for 35 bucks
