CARBURETOR - Idle Speed and Mixture Ratio (Models with catalyzer and E.G.R.) (Cont'd)
EF & EC-154flowchartIgnition timing differs by engine: 2° B.T.D.C. (GA16DS), 0° B.T.D.C. (GA14DS). Idle speed differs by transmission: M/T 750±50 rpm, A/T 850±50 rpm in "N".

(A) connector from previous page
2
Disconnect boost pressure sensor vacuum hose and install blind plug to hose.
3
Loosen distributor securing bolt, and adjust ignition timing by turning distributor, until ignition timing is 2° B.T.D.C. 2° B.T.D.C. (GA16DS) 0° B.T.D.C. (GA14DS) (in "N" position)
4
Connect boost pressure sensor vacuum hose.
5
Race engine (2,000 to 3,000 rpm) 2 or 3 times under no-load and run engine at idle speed.
6
Check idle speed. IDLE SPEED: M/T: 750±50 rpm A/T: 850±50 rpm (in "N" position)
N.G.
Adjust idle speed by turning throttle adjusting screw.
