It mearns that the computer is sensing a failure. You will need to see if it has logged any codes, and troubleshoot from there. You can go to many auto parts suppliers (autozone, ect) and many will read the codes for you, or you can purchase code reader and do it yourself

Engine starts then die when idling, changed fuel pump and also magnets (COILS)


I had the exact same problem with my 2003 Galant. The above solutions may be correct but try some other things first.
1) start car and with engine idling turn on the AC. If the rpm's drop and don't come back up or the car dies, it is probably a dirty max air flow sensor. This is an easy fix even for a novice. Many you tube videos to show you how to clean.
2)check spark plug wires and boots. Cheap solution and a likely culprit.
3)Is your service engine soon light on? Could be an emissions problem. If you are able to drive the vehicle and notice that even at highway speeds you slow down with pressure on the accelerator you may have to replace something in secondary emissions control. Not likely.

If it is a vac. hose leak you should be able to hear it and locate it with your hood up and engine running.

TCL is controlled by ABS system,could have an abs sensor going bad. There is alot of things that could cause a misfire,mass air flow sensor could be dirty or need replaced.Best bet is to take to someone with computer that can read what all sensors are doing in vehicle.

2003 Galant 4cyl .. After not knowing Car timing belt was what broke ..Car was attempted to turn on various times... How will I know if I have to re-built the engine ?


The Galant has an interference engine, when the timing belt breaks the valves stop and the pistons strike them. At the least you need a new head. There is really no way to tell how much damage was done without tearing the engine apart.

I have a 2003 Mitsubishi Galant ES and after checking my oil, my service engine soon light came on, it is time for an oil change, can this be the reason for the light or is it something more?


if your talking about the check engine light being on, no, it will not come on because of oil service time. you may of left something off. if the dipstick or oil cap is loose this could set a code.

Service engine soon-2003 mitsubishi galant, 87000 miles


it might be the a couple of thngs...

1)catalytic converter messed up
2)oxygen sensor before or after the catalytic converter needs to be replaced.
3)belts need tightening
4)your fuel cap has not been well tightened.

go down to a mechanic and have them check your engine light. They most likely will have a computer to check and narrow down what might be the problem.

The "Service Engine Soon" light came on in my 2003 Mitsubishi Galant. Is this an emission related issue?


More than likely it is, but you will need to have the codes scanned and description of that code to know what the cause is.
