TUNE-UP DIAGNOSIS
Engine tune· up has lang been the term used to indicate almost any
group of service operations covering repciirs
and ~djustmen ts of
the
ignition, compression, and carburetion systems on automobile
engines. Many car owners in the past years have had, at times, the
experience of having their cars "tuned up" only to lind that the
trouble they were experiencing was not corrected.
In trying to avoid this difficulty, tune· ups which included just
about every service that could
be
done on an engine were recom·
mended. While these complete tune· ups were successful in correcting
many troubles, they were expensive and owners sometimes paid for
a lot of service they didn't need.
To assist owners in getting what they need· and avoiding unneces·
sary expense, many Pontiac dealers are offering a specialized
Tune·Up Diagnosis Service. This includes: First, the few minor
adjustments to the ignition, compression and carburetion systems
needed at regular intervals; Second, a group of minor lubrica tion,
and maintenance jobs on the e lectrical system needed twice yearly
