) But didn't the refridgerator play for the Lions or was it the Steelers? My NFL history is not very extensive!If the code 131 keeps coming back after replacing the O2 sensor, then it's been my experience that a vacuum leak exists somewhere. The less time consuming way of locating a leak is to assemble a smoke machine of some sort with a tube inserted into the vacuum tree (after disconnecting the large hose to the air filter). Check u-tube for how to put one together. I used a large glass container, a few brake cleaning tubes, and a small motor that is used to inflate small swimming pools (enough to blow the air into the container to keep the smoke burning). I used some small twigs, but others have used sage, a tipped cigar, charcoal, and even a cloth soaked with baby oil heated with a handheld electric soldering tip. Again, u-tube helps provide options on how much of a supply of smoke you need. Some have used a spray can of carb cleaner or MAF to locate a vacuum leak - if the idle increases after spraying a certain area, then you've likely found the leak!
