Stealth R/T Turbo V6-2972cc 3.0L DOHC Turbo (1996)
Ignition Timing Adjustment Terminal Grounded
4. Remove the waterproof female connector from the ignition timing adjusting connector (brown).
5. Using a jumper wire, ground the ignition timing adjusting terminal.
6. Start the engine and run at idle.
7. The basic idle speed should be: 700 RPM (±50 RPM).
The engine speed may be low by 20 to 100 rpm while the vehicle is new [distance driven approx. 500 km (300 miles) or less], but no adjustment is
necessary.
If the engine stalls or speed is low despite a sufficient distance driven [approx. 500 km (300 miles) or more], it is probably due to deposits on the throttle
valve. In this case, clean the throttle valve.

The tachometer should read 1/3 of the actual engine speed. This means that the actual engine speed is the tachometer reading multiplied by 3.
Adjusting The Idle Speed
8. If the basic idle speed is out of specification, adjust by turning the engine speed adjusting screw.
NOTE: If the idle speed is higher than the standard value (even with the Engine Speed Adjusting Screw turned fully "in") check to see if there is
evidence of the closed throttle position switch having been moved. If the closed throttle position switch seems to have been moved, adjust it. If it does
not seem to have been moved, there may be a leak caused by deteriorated Fast Idle Air Valve (FIAV). In such a case, replace the throttle body.

9. Turn the ignition switch "OFF".
10. When the scan tool has not been used, remove the jumper wire from the diagnostic test mode control terminal.
11. Remove the jumper wire from the ignition timing adjusting terminal and replace the connector back again.
12. Start the engine again and run at idle for 10 minutes to make sure that the engine runs at proper idle speed.
