12) Optional Retest - 1987 & Newer
• Lightly press and release throttle
within 2 minutes after the last code
is sent. This will repeat the entire
cylinder balance test.
• IMPORTANT: (Some 1987 and all
1988 & newer) Repeating the test
can tell you how weak a bad
cylinder is. (The computer alters
inspection during retest.) Test
results will be different for a good,
weak or “dead” cylinder. See charts
below using cylinder #7 as an
example.
