If anyone can help, I have 98 XEDI L SERIES. When i switch on the lights the power drops if i remove my foot and then accelerate its ok for a while and then drops off again. It only happens when lights are on. I can have all other electrics on, no problems! Help...

The model is a 98 xedi swagon. The reason i got auto electrican out was for a minor fault wth reversing light switch. New owner of a landy so lay off with your sarcastic comments:D

The car is a 98 xedi swagon

Got auto electrician out. He said timming injection pump deviation. Possible pump/injector defect. Any Ideas? Good Landy garages in glasgow?
