My metro idles very low and dies when I come to a stop. It also dies when I turn the lights or the heat on, or put it on gear. I have to keep my foot on the gsd to keep it from dying. Help!
EGR stuck open is #1 stall failure.
SOURCE: 1991 geo metro rough idle
i have no idea about an idle up solenoid relay but i had the same problem.. there is a hex screw on the motor that takes a very small allen wrench head where you can adjust the idle from there. its near the throttle body
SOURCE: 94Metro Has a bad vibration at idle, gets worse in gear stopped
check all motor mounts first. if they are ok then check to make sure all cylenders are firing. try pulling one plug wire off the spark plug and see if the engine changes sound or anything. if it does, put the wire right back on then move to the next one and repete. if you pull one and it does not change then that plug is not firing. could be caused by a crack in the porcelian in the plug or bad plug wire connection or bad wire

Try this
Here are the most common causes of surges, stalls at stops, low erratic idle speed, rough idle and engine hesitation, it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
SOURCE: transmission fluid for 94 geo metro
An automatic transmission on a 94 Geo Metro takes Dexron II (or higher- ie Dexron III etc) type transmission fluid only.

Had similar issus with mine, turned out that egr valve was about 90% clogged-pull off egr and make sure opening on back side port is about the size of a nickel, if not-clean out-should clear it up---best of luck
