Ok so on my 2000 4.0 Disco I upgraded to Magnacor 8mm wires and while I was in there I replaced the valve cover gaskets and cleaned the IAC, with carb cleaner. I did this hoping to alleviate a rough idle and poor fuel mileage (yes I know I will never get great mileage). The idle has smoothed somewhat, except coming to a stop after accelerating, and now during acceleration it feels like I am pulling a trailer. I'm ready to just start throwing parts at it, sell it, or burn it to the ground. Not sure which will get me my best return or the most satisfaction. Any help would be greatly appreciated. Thanks!!
