    It's 2002 and just had CAI installed and now under heavy acceleration I throw a light. After I park the truck for s bit it turns off and is fine I cant feel any differenceat all. Not sure what's going on. any ideas?

    Could be getting a lean condition at heavy acceleration dut to the increased amount of air now entering because of the CAI.

    Did you disconnect the battery for ten minutes after you put the CAI in?
  4. Check for air leaks, retighten the cai clamps.
