You will need to pull the trouble codes out of the computer to know what area to look in.I have a 91 Galant,and it recently had similar symptoms,and kept setting two codes,an Air Intake Temeprature (AIT) code,and a motor position code.Turns out,the Air Intake Temp sensor is actaully built into the Mass Air Flow (MAF) sensor.Replaced the MAF,and both codes went away,for good.So it is essential to pull the codes as the code definition is the diagnostic route/area of the problematic system.It could very well be the O2 sensor though,and if you don't mind spending money,replace it and see what happens.Disconnect the negative battery terminal 20 minutes to reset the computer and clear the trouble codes.Good luck

89 celica starts and runs good after it get warmed up you shut it off it will not start just dead what is the cause of this problem?

You will need to figure out if it is a spark or fuel problem to proceed.
Could be a list of things including the coil or igniter, fuel pump or relay, or other things.

When I start my car up it runs slugish till it warms up then it runs great?

Could be a number of issues, but if your coolant sensor is reading wrong, your fuel system will introduce more fuel causinga poor start. You can read this data with a good scanner.

4G93 Mitsi Galant motor suddenly stops dead when running, but will not start again till cold then will only run for 8 minutes approx.

I'm not 100%, but check your crankshaft positioning sensor, or the mass air fuel sensor. one of those may be the culpret.

Run good till the check engine light go off

Check the fuel lines under the car. Don't actually start the car though, just turn the key until you hear the fuel pump turn on. This will load the fuel system and you will be able to see leaks (or sprays) under the car because of the pressure. If there are no leaks, see if the car runs perfect with a full tank of gas compared to a low tank. It should drive good turning left, but it might **** turning right or after a sudden stop. This could mean you have a crack in the seams of your gas tank or that your fuel pump is going bad (or a little of both).

Look for Vacuum leaks. PVC and EGR valve, Line from brake booster, there is also a small hose right under Throttle body( hard to see but keep looking till you find it is there.) Next tune -up (plugs $8 and wires$20).

Many things can effect an engine during the cold.

I'd start by doing other basic tune up replacements. Such as an Air Filter, PCV valve, Fuel Filter, Oil Change. All things things keep an engine healthy.

Another thing to try is a bottle off fuel system cleaner. I recommend such brands as prestone, lucas oils, or STP. These will help eliminate deposits on the fuel system and help keep the fuel and air moving.

Did you replace the plugs with pregapped plugs? If your plugs aren't gapped right this could happen as well.

Hope these ideas help you out bud!
