My engine light came on several weeks ago so I took it to a local garage. They said that a cam sensor problem was indicated and so they changed both cam sensors. Several days later the light came on again so they re-installed the sensors. Again, a couple of days later the light came on again so they changed the crank sensor. The light came on again today and I don't know where to go from here. Back to them to turn the light off again for a couple of days?

 

Apparently it's not a sensor, they should start looking for a chaffed wire or a corroded connection.
