robp823 Posted September 4, 2009 Share Posted September 4, 2009 99 f-350 V-10.Well i got this one thrown into my lap today.Customer had heads off due to spark plugs breaking and had to put 2 new valves in one of the heads.When you start the truck up its goes right to 3 grand and stays there.If you give it throttle it will climb and wont come back down.So just for the hell of it i had a spare IAC so i swapped it out.Started up , idled rough a couple seconds then stalled.Started it back up again went right to 3 grand again and stayed there.shut it off Start looking around the engine for anything obvious and nothin.So i started thinking maybe its sucking air somewhere it shouldnt.So i went to start it again and it dies and all i smell is fuel.Went to start again and the starter takes a shit.No codes, when it did run SFT are at -7.

Brad Clayton Posted September 4, 2009 Share Posted September 4, 2009 The only I've got that comes to mind is.....you seem to get all the shit work! Hope your dealer and comrades value your presence in the shop. If I was there and you decided to pack it in, I would do whatever possible to change your mind, so I wouldn't have to work on them junkers. By the way unplug the MAF and see what happens.

Brad Clayton Posted September 4, 2009 Share Posted September 4, 2009 Brake booster hose should be about the easiest place to get smoke in there. Quote Link to comment Share on other sites More sharing options...
GregKneupper Posted September 4, 2009 Share Posted September 4, 2009 Check your tp mode pid and make sure that it reads c/t at idle. If it reads p/t then you may have a bad tp sensor. Try reseting kam after verifying the pid and see what happens. Quote Link to comment Share on other sites More sharing options...
