im sorry, i think i described the wrong cylinder, the one farthest from the fan, whichever one that is. the pan oil temp sensor i just replaced, but that one never had a high reading. i had the engine head temp light come on. if i would idle down it would shut off with in seconds. it was doing this occasionally before the injector went bad. i thought high temp might have had something to do with the injector. i also operate on step hills, if that could do anything. thanks again for everyones help.
