If, from the time the vehicle was new, the routine maintenance schedule is followed closely and frequent checks are made of fluid levels and high wear items, the engine will be kept in relatively good running condition and the need for additional work will be minimized.
More likely than not, however, there will be times when the engine is running poorly due to the lack of regular maintenance. In such cases, an engine tune-up will be needed outside of the regular routine maintenance intervals. The first step in any tune-up or diagnostic procedure to help correct a poor running engine is a cylinder compression check. This check will help determine the condition of the internal engine components and should be used as a guide for tune-up and repair procedures. For instance, if a compression check indicates serious internal engine wear, a conventional tune-up will not improve the performance of the engine and would be a waste of time and money. Because of its importance, the compression check should be done by someone with the right equipment and the knowledge to use it properly.
The following procedures are those often needed to bring a generally poor engine back into a proper state of tune.

Minor tune-up

Clean, inspect and test the battery
Check all engine related fluids
Check and adjust the drive-belts
Replace the spark plugs
Inspect the distributor cap and rotor
Inspect the spark plug and coil wires
Check and adjust the idle speed
Check the PCV valve
Check the air filter
Check the cooling system
Check all under-hood hoses

Major tune-up

All items listed under minor tune-up plus....
Check the EGR system
Check the ignition system
Check the charging system
Check the fuel system
Replace the air filter
Replace the distributor cap and rotor
Replace spark plug wires
