Is this the big 1?
I know the cambelt has to be done.
Also i've recently had my ecu light on for many reasons recently all replaced i think!! (as in i can't tell if it actually is!)
But now it seems as though a secondary air pump that warms up the cat on cold starts is causing the problem? and the light is on again! But would this cause my ecu light to come on? And would this be a problem like blow my engine up!!
