About 2 weeks ago my check engine light came turned on so i drove home and told my dad about it but when we turned the car on it did not flash. But the the next 2 days it stayed on and the next morning when i turned the car on the car turned off no more than 3 seconds after. Dad tries it and the car still turns off after a second or two. Tries it again a couple hours later and it drives fine

Any time you get any check light, you should
be at a repair in a couple of days, or at least
check for codes. Still need it diagnosed and
repaired in a week

Otherwise you waste gas,polute the air or could
cause some damage,as you don't know what the issue
is that set the light

The fact the check light went out, doesn't mean
the problem went away.

Don't clear any codes you find,their needed to diagnose
the system faults
