Hi folks, new to the board. 08, 4.6L, 2WD ST Limited. K & N CAI, Gibson exhaust system, SCT tuner, 87 octane. No other modifications. Getting moderate knock / vibration after acceleration onto freeway above 60 / 65mph. Lasts for a minute or 2 then goes away. Otherwise runs great!
Can't tell if it's motor or drive train. Looking for any ideas / suggestions to isolate problem. Any help is much appreciated...
