On a 500mile trip today.. About half way I stopped to grab something to eat.. and went to park.. and it would not idle all the way down.. about 1050.. was it... so I left it running for the trip... got to where I was headed.. and then shut it down.. restarted it.. and it was back to normal... No codes came up, by cycling the key...
The Comp on or off did not make a difference.. fuel pressure and everything else looked good.... She rolled 187K today.. Orginal VP.. (the second LP was still running fair.. but I'm trying something else for a while...)
Clean the APPS, and reset its position???? Anything else I should look at???
Thanks,
Bryan
