What can be the problem?
Well, the first problem is that you've posted in a thread that was started 4 years ago.

I'm personally interested in what you mean by "fuel injection switch"- is that a relay? There are no switches in the EFI circuit. I'd be taking it back to that mechanic and asking him why this problem wasn't there before he worked on the car.
