I guess it is an easy fx for all those 'check codes'. Who needs to change sensors, plugs, coils etc... anymore? (joke)
Well, after all, it's my wife's car.
Was it a maint req light or check engine light? Resetting the maint req light is much different than the check engine light. The maint req light tells you it is time to change the oil and get the scheduled maint for the mileage your car is at. The maint req light would not come on after 8 days unless you drove for about 5000 miles in that time period.
