  1. Check all vacuum hoses for incorrect routing, restrictions, cuts or other damage. Inspect hoses beneath air cleaner assembly and other engine components.
  2. Inspect all wires in engine compartment for correct and good connections. Also check wires for pinched or chaffed spots, as well as contact with sharp edges or exhaust manifolds.
  3. Perform preliminary inspection CAREFULLY and THOROUGHLY. A thorough inspection often leads to fixing a problem without further diagnosis.
