Preliminary Inspection

  1. Check all vacuum hoses for correct routing, restrictions, cuts or other damage. Inspect difficult to see vacuum hoses beneath the air cleaner assembly and other engine components.
  2. Inspect all engine compartment wiring for proper connections. Also check wires for pinched or chaffed spots, as well as contact with sharp edges or exhaust manifolds.
  3. The preliminary inspection is very important and should be performed CAREFULLY and THOROUGHLY as it can often lead to fixing a problem without further diagnosis.
