Turn the idle screw to adjust the idle—turn the screw to the left to increase the RPM or to the right to lower it. When you have adjusted the idle—aim for 650 RPM—reconnect the idle air adjustment valve’s electrical connection. Lower the hood and turn your car off. will make sure your insurance does, too. Reinstall the mixture screw and adjust to the original position. If the idle smoothed out, then turn it in until it runs rough, then back off until it smooths out. If it is still rough then, back off the screw until it smooths out. If it doesn't, then the carb will have to be overhauled. D. Check the ICM (Erratic RPM and PGM-FI System) When the engine is cold, the air conditioner compressor is on, the transmission is in gear (automatic transmission only) or the alternator is charging, the ECM controls current to the Idle Air Control (IAC) Valve to maintain correct idle speed. Here's an overview of how the PGM-FI System works. When the engine is idle, the throttle body is supposed to adjust the opening to maintain an ideal idle speed. As you turn the AC on, the throttle opening should adjust itself to maintain a proper idle speed even with the added load. However, a clogged-up throttle body fails to do that and causes insufficient air to pass through, putting more Page 180 EG2–180 1MZ–FE ENGINE – ENGINE MECHANICAL (c) Hold the crankshaft pulley bolt with a wrench, and install the 6 bolts evenly. Torque: 41 N–m (420 kgf–cm, 30 ft–lbf) HINT: First install the dark green colored bolt, then install the other bolts. (d) Install the flywheel housing under cover with the 2 bolts. Very useful in setting idle speeds and working on car electricals. The VSV actuates a vacuum diaphragm which is connected to the throttle plate. This vacuum diapghram pulls on the throttle plate a little in order to increase the engine rpm whenever the AC turns on. If you goose the throttle a little to move the linkage, the solenoid will keep it on higher idle, but won't push the throttle off the stop when it actuates. Maybe this GM one works better. FYI - I just brought the A/C back online for my '75 GMC, and so far it doesn't seem to need an idle compensator to run smoothly. 1. Start engine and warm it up to normal operating temperature. 2. Rev engine (2,000-3,000 rpm) two o three times under no-load (A/C OFF, headlights OFF, radio OFF), then run the engine at idle speed. 3. Adjust the idle speed by turning the idle speed adjusting screw.
