Hi, my name is***** first thing you should do is a fuel mixture adjustment. Click on the attachment below for the procedure. It's also possible that your fuel distributor is faulty. I'd try the mixture adjustment first. Also make sure that the overvoltage protection relay is good. The relay powers the engine management system.

Let me know if you have any questions.
