Just filled up and the 4Runner got 9mpg. Granted she's SAS with 35's but looking for tips as previous owner had the distributor off a tooth, timing mark so far advanced the mark was basically pointing at the passenger frame and the AFR messed with. I've never heard it knock so I'm guessing I'm going deaf or the computer is retarding. But for those with this setup, what was your sweet spot on the AFR wheel? My understanding is timing should be set at 5% degrees with the jumper wire. I have a standard timing light and vacuum gauge. I've replaced plugs, air, and fuel filters. Thanks in advance!
