GENERAL
Power plant diagnosis is helpful in finding the causes
of problems not remedied by normal tune-ups. These
problems may be classified as mechanical (a strange
noise, for instance), or
p e r f o r m a n c e
(engine idles rough
and stalls, for instance). Refer to the Service Diagnosis
— M e c h a n i c a l c h a r t a n d t h e S e r v i c e D i a g -
nosis—Performance chart.
Other tests and diagnostic procedures may be neces-
sary to pinpoint a particular problem. Information is
provided under Diagnosis With Scope Analyzer, Com-
pression Test, Cylinder-Leakage Test, Blown Cylinder
Head Gasket Diagnosis and Intake Leak Diagnosis.
