The following is a list of sources to obtain vehicle service information for your
specific vehicle.
• Contact your local Automotive Dealership Parts Department.
• Contact local retail auto parts stores for aftermarket vehicle service
information.
• Contact your local library. Libraries often allow you to check-out automo-
tive service manuals.
Do a Thorough Visual Inspection
Do a thorough visual and “hands-on” underhood inspection before
starting any diagnostic procedure! You can find the cause of many
problems by just looking, thereby saving yourself a lot of time.
• Has the vehicle been serviced
recently? Sometimes things get
reconnected in the wrong place,
or not at all.
• Don’t take shortcuts. Inspect
hoses and wiring which may be
difficult to see due to location.
• Inspect the air cleaner and
ductwork for defects.

damage.

- Damaged terminals.
- Split or cracked spark plug
boots
- Splits, cuts or breaks in the
ignition wires and insulation.
