How do I find an idle stop screw for a 1993 geo metro?

If it has a stop screw, look on the throttle body assembly where the throttle control cable hooks on- the gas pedal cable running from the lower firewall to the engine. You can rotate the throttle control by hand, but where it is in the at rest position- as at idle-there would be a stop screw on the throttle body, which can keep the throttle control from closing further.

Motor runs at 4000 rmp when started

1995 Geo Metro. COLD start or HOT started or BOTH?
Does it ever idle down to 800 HOT? (engine temp)>?

Geo Metro (later re-branded the Chevrolet Metro), Pontiac Firefly, and Suzuki Swift
which engine, what country???
I will post for USA only !!!!
Auto or stick tranny???
the USA 1995 was the last car to use TBI injection (throttle body)
the LSI option, then had a 4 cylinder. in 1.3Liters.
and works totally differ. than any 1.0L
answsering for 1.0L

Have you inserted the Diagnostic jumper wire and looked at the
FLASH codes yet?
choke? on 95? what country is this, ours are not carbs. in 1995.
so post country. ours are all EFI in USA.
3 cylinder? 1 liter? or which engine/?
on any USA Metro, 1L , when first started, it has 2 valves. to control IDLE, (cold , is iAC) hot is ISC, The cold start valve opens farther the colder it is (how cold was it). but usually is limited to about 2000 rpm
this engine, TBI, uses a MAP to control fuel mixtures, and
any air leaks (aka; vacuum leaks) what so ever, will cause too fast idle.
so on MAP cars, you get to find out what is leaking AIR.
1995 has the new better , idle control speed motor, (ISC)
this can be stuck open.
that new TPS, did you do the calibration correctly?
it must set right. or idle will never be controlled.
finding the cause, takes hard work, and hands on testing
A/C fast idle broken
A/T transmission fast idle, device, broken.
Air leaks (add huge list of possibles and cracked hoses here)
Throttle stuck
ISC or IAC bad.
very hands on to find this, done many.
TPS on indexed corrrectly or not calibrated.

I have a 1997 Geo Metro 1.3L that starts but has no power. Can not drive it. The code is P0505 idle control malfunction. I checked the fuel pressure and its ok. Whats next?

Idle control, only controls idle, it will not cause no power, and that code could have set, due to no engine power, check fuel filter that it's not clog, could have good fuel pressure, but under load not getting enough gas, also check timing belt, if it jump a tooth, will cause no power, here's a figures so you can check timing belt.3d3d9e0.gif

1992 geo metro 1.0 engine seems to flood and idles high can't adjust idle it's low as it goes and still idles high timing is right on any suggestions?

You might also check the single injector, had a friend's that the fuel pressure regulator had been messed with and was over-pressurizing the injector, that weakened the injector allowing it to flood at idle and also when cut off (the injector was leaking)

Gas mixed the engine oil and ruined the engine.

The only way I can think of that raw gasoline could get into the oil is at the thottle body. So, the fuel injector or fuel line in the throttle body would be the first place to look if you're sure that it's gas in the oil and not another fluid.
