Does anyone know the magical position to dummy o2 sensor?

Awhile ago I straight piped my 95 awd and it has been trowing check engine light. I got a new o2 and am going to install it outside of the exhaust stream to sens correctly but I don't know how far out to mount it. I used 2.5" exhaust tubing, has anyone successfully done this?

I have used spark plug anti foulers for this. If you stack two of them together and pack some steel wool in the bottom one it should work! Hope this helps

Sounds like a plan to me. Is anyone running this setup?

Or you could return the O2 you just bought and build one of these and not have to worry about putting a hole in the pipe or putting a bung on for your new O2 that you don't need a reading from.

Wrap the O2 in tin foil and zip tie it up to the body of the car. All its looking for is a difference in the readings between the front and rear sensor. I never had an issue doing this.

The tin foil method did not work on my 97.. The only way i got rid of that CEL was through link.

i used the spark plug non foulers on my old cavalier...just take one and drill it to 1/2 inch and to sensor will fit right in and put the undrilled one on that... never once threw a light had it that way for 3 years..
