XJ runs rough and cuts out

Unread post by XJalltheway » April 18th, 2016, 1:32 pm

G'day all, my XJ has been sitting for a fair while, and now whenever its running for more than half an hour it starts to splutter and run really rough, and starts revving all over the place, and eventually cuts out completely. Before I parked it up, I had overheated it (forgot to turn the fan on while wheeling). What might the problem be? I suspect it may be a blown headgasket. However the fuel in it is a few months old, so would it be just a case of bad fuel? I don't want to pull apart the engine if its simply some off fuel.

Cheers, Jim
