Question

Got car serviced for check engine light...fixed light off...week later on, then off again 4 days later. Should I worry?

Answer 1

HI there

You should have the code read to find out why the light was on. You can only do this when the light is on, otherwise there won't be any codes stored. If the car is running fine even when the light is on then it's likely a problem with the evap emissions system.
