hello i have an 89 Jag Xjs V12 The car starts right up but idles rough.and it smokes black smoke from tail pipes at idle and also when driving i took out the two plugs I could reach and the one was heavy carboned the other was black also but wet with fuel. Also when I changed the oil it was diluted with fuel.I was wondering if this has to do with the fuel regulator dumping to much fuel to the injectors? or ??? thanks CaM
