HELP. Here's the rub.
1993 300E (california car), bad mechanic damaged the head while removing, replaced the head with a non-california head, no big deal as I am not in California, however there were no fittings on the head for an air pump.... They blocked the pump off and everything runs fine, passes emissions, however....I have a constant engine warning light. Now the vehicle is in my shop and the costomer really wants the light off so that if there is a problem she will have some warning - and probably just wants the damn thing off. Any help would be great and, yes I did suggest putting the correct head on which she declined to do.
