constant ‘engine’ light???causes and cures
Have the codes read to have a clue as to why the light is on - fix what ever the codes relate to.
The cause: Your engine has a problem
The cure: We will never even be able to guess at a cure unless you have the codes read and post them here. And we want the numbers in the format P1234. All of them.
Would also help to know the engine size, transmission, mileage and how long that CEL has been on.
