Question about 2002 Mitsubishi Galant
No issues until today, was driving home from and and engine spurted a couple of times and then started running great, but Service Engine soon light came on and stayed on. Had it check at Auto parts store and they said was random. It had also rained today and they think it git wet. Oil OK,not running hot, checked gas cap, so what could iut be?
You have a real auto repair shop ( not auto parts store) look at stored codes, & any freeze frame data
Do not clear the dash light or you loose data & ability
to diagnose & resolve the issue

The most common reason for an engine light to come on is a bad oxygen sensor. There can be many reasons for the light to come on. Most auto stores will plug in an engine analyzer and read the engine codes for free. At that time, they can also turn off the light. The stores motivation for reading your codes is to sell you the parts to fix it. A bad oxygen sensor will allow the car to run normally , only your gas mileage may suffer. Anyway let the car tell you what is wrong with it.

THE OIL CHANGE INDICATOR WILL NOT CAUSE THE SES LIGHT TO COME ON.THEY MAY HAVE LEFT SOMETHING DISCONNETED NEAR THE AIR CLEANER HOUSING WHEN CHECKING THE FILTER.IF NOT HAVE CODE READ(SHOP/PARTS STORE)

The service engine light is totally safe. If it's just the ABS light, it's safe as long as you don't panic stop on the way to the shop.

Tips for a great answer:
1.Fuel injectors, related wiring, sensors, computer issues
2. Running out of gas, or poor fuel quality
3. Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
4. Incorrect Fuel Pressure
5. EGR system concerns: leaking EGR valve or restricted ports
6.Base engine concerns: low compression, valve train problems and timing issues
7. Ignition system concerns including, but not limited to:
Faulty spark plugs
Faulty coil or related wiring
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues
You will have diagnose each element until you find root cause.
And it could be more than one element faulting out.
