Engine Performance problem
1990 Mazda RX7 Two Wheel Drive Automatic 125000 miles

Engine will not idle with the air conditioning on. Seems to idle to low, sometimes kills when I brake to a stop.

Manual cautions not to increase idle because it will chainge the shift points causing transmission problems.

Check if it has an idle up solenoid if it does test it-its job is to increase the idle speed when the clutch engages the compressor due to the added load on the engine
