When cold my '93 suburban dies but once warm runs fine it has a 454 with tbi


Have you checked to be sure the idle air control is working properly and also the engine temp control sw. The iac only comes on to maintain the idle when the engine is cold. The ect sw monitors the outside temp and tells the computer how much fuel to put to the engine. Hope this helps.

92 chevy idles real fast on cold start up, then after run warming up runs fine


Not an uncommon issue for one to idle fast while cold but , 2000 rpms is a little higher than normal. May want to check the engine coolant temperature sensor for proper voltage and the coolant level. Also, check for small vacuum leaks around the throttle body gasket.

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)>?

Aka:
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
max.
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.

1993 Chevy C1500 4.3L V6 TBI starts but dies at idle after warming up.


Low pressure from fuel pump, when the pump is cold the pressure increases, as it warms up the pressure drops (this happens in a pump that is going out) the normal pressure should be at 40 with the key on and engine not running, when started the pressure should stay around 36, any less it won't idle and may run as long as you hold the pedal down. The injectors are opened electronicaly, so as long as there is fuel flow the engine gets fuel to run.So check the fuel pump, soundslike you need a new one

1990 full size blazer starts fine idles then dies


sounds real easy either a bad idle air control solenoid or more likley a blown throttle body gasket. to test fro a blown gasket, with engine running and cool spray carb cleaner or brake cleaner around base of tb were it bolts to intake. when it hits the bad area, should idle down and be normal for a second or 2. iac is possible,try this first since its so common and let me know

High idle


You could have a bad gasket under the TBI that is allowing uncontrolled air to enter the engine or an Idle Air Control Motor that is not working properly.

Cold Start Idle Issue


Problem might be the air control valve, it's located at the right side rear of intake manifold and has a hose going to the air intake duct from the air cleaner, as a test you might try pinching off that hose when the idle is a problem.
