I have a Mk4 Escort cabriolet which has mk4 escort wiring loom, with Fiesta turbo add ons,its got a 195 chip with beige injectors,t3 turbo and a high boost cam,i am having problems with it over fuelling.Its had new fuel pump,and regulator,injectors have been changed to standard but made no difference so i changed them back.Does anybody know of any known electrical problems with these after having this conversion??
