Escort Sringt on and off again

Hello and good morning , My Escort Cabrio Bj 1991 makes a little mute He jumps on and if you want to give some gas he goes out again. I turned out spark plugs times and cleaned out but no change.Now yesterday was the ADAC times because he has sprayed at the front of the distributor and then he has also run – until the man has stopped spraying He meant then the fuse box must have new boxes so around the 250€ and the gasoline pump would not run . What can I do to determine what I have to get now ? I need my car and do not want to give it to scratch Hope one of you has good tips
