The check engine light stays off . It runs decent. Im just curious if this is something that works or am I handicapping it by running it this way. Will the o2 sensor read close enuf just from the one side? Or should it have a y-pipe to work properly? Thanks!

You should put a Y pipe in it if it only has 1 o2 sensor unless theres some way to modify the computer so that you can have it read a second sensor. Right now the bank that doesn't have an o2 sensor could be running super rich, super lean, misfiring, etc...and you would have no idea.

Rick Maybe I'm missing something but how would the computer know how rich or lean the other bank is running, especially on a smpi engine? Last edited by chache876; 01/09/11 12:19 AM.
