Is the Atomic EFI
controlling the engine’s
ignition timing.

Then shut it off and
start it again.
Letting the engine run at
temperature for 10
minutes will allow the
system to start learning.
Has the throttle been

Refer to page 14 of the
instructions to ensure
the throttle is set for
your engine.
Refer to page 13 to
learn how to correct
and clear codes.
Does the Handheld

during
cranking/idling?
Is the engine hard
starting?
Refer to pages 4 - 6 for

The engine is easy
starting. Does it idle
well?
Has the engine had the
chance to idle for 10
minutes at operating
temperature 160° or
above?
Allow the engine to idle at
running temp. This will
allow self-tuning to adjust
items as needed.
Are there any vacuum
leaks?
Ensure that there are NO
vacuum leaks that could
affect the amount of air
in the engine.
Are you sure the
ignition timing and
rotor phasing are
correct?
Are the throttle blades
adjusted for the
engine? See page 14
The IAC can only do so
much to ensure the right
amount of air gets in the
engine. Refer to page 14
for throttle adjustment.
Does the idle Air/Fuel
Ratio make sense?
Excessive Lean or Rich
targets can make it hard
for an engine to idle
steady. Use the
Handheld to double
check the target to
ensure it is appropriate.
Does the engine idle
well?
If each of the aforemen-
tioned items checks out and
the rough idle issues still
exists, please contact MSD
Customer Support at
915-855-7123.
The engine idles well!
Go to the next page.
If timing is off an engine
can struggle to idle
regardless of the fuel
system. Make sure the
distributor is in proper
alignment.
