Well my truck is acting up again. I've noticed in the past week that once in awhile when i'd first start the truck up it would have a rough idle for about 5 second and then stop (it would sit for about 30-45 seconds before doing it, not right at start up) but it would stop right away so I didn't think anything of it. Well today at a stop light it started doing it and hasn't stopped. So I got home and started checking it out. On the drive home it seemed to have the same power as normal, made normal boost but the boost was jumping guessing due to fuel pressure being jerky, didn't smoke at all, no check engine light, all temps and gauges were fine. Got home fluids are fine hasn't used any oil, yesterday I drove 150 miles on the freeway after putting fuel in and it did fine so the gas can't be bad, plus I switched to the other tank and drove most of the way home with the gas that was in before yesterday and then drained the bowl. the only problem is its got a real choppy idle the cakkling is real bad almost like turning the swtich on for the 10K, but the tach is reading a steady RPM its not surging with the engine, and at the exhaust it sounds normal, doesn't sound like its rough idle back there. I looked in the fuel bowl when i drained it and what are those 3 or 4 little round magnet looking things on the bottom? Because one is gone and one was cracked and i picked up the half that was cracked and laying there, this is scaring me, i'm wondering if the one that fell off went threw the engine or is in the engine still? When i would start to go the truck would shake real bad and but then at like 1800rpm it would smooth out, so i'm stumped.

Anyone have an idea of what it could be? I thought maybe a motor mount was broke because I've been having a problem with it pulling when i'd make a left hand turn and get on the throttle at the same time, and then the way it was acting today the engine was jumpping around alittle but I checked and they're fine. Thats what it seems like, seems like the engine is shaking alot but not running bad but I dont know. Any help or ideas would be great. Thanks guys

 

maybe watter in fuel? could be your oil pressure regulator? not the one on filter. the one on the back of oil pump. o rings sometimes go bad, if it been running bad for at least 500 miles, it not sugar, hopefully you have locking gas caps on your truck,

 

But like i said i drove 150 miles yesterday with this gas I just put in and it was fine but then today after driving another 30 miles is when it went bad, it was in the garage also so no one messed with it. As for o-rings wouldn't it smoke or use oil? I'm thinking maybe ICP sensor since that normally gives a rough idle. Wish a code would show up so i'd know where to look.

 

Well I think i found it. The front wire harness that goes into the valve cover the farthest pin back is all melted.

Anyone have a part number for this or a write up on how to replace it? Anyhelp would be great again. fun fun.

 

title that farthest pin goes to the glow plugs. you could be headed in the right direction. do you know of anybody with a scanner capable of buzzing the injectors????
you may wanna bookmark this page all you need and then some.... joats parts page this is the mamma jamma

 

Contact Kwikkordead, he had a thread on this about a year ago, he would be a good source. He also posted pictures.

 

No don't know of anyone that can check the injectors.

I really think its that plug thats causing this, but no check engine light came on? I got all the part numbers for the plugs, wires with pins, valve cover gaskets, and the under valve cover harness so I'm gunna run and get it all to do the one side, other side seems fine. Possible that because the farthest one is completely melted and almost into the second one up that its sending signal to that one and messing it up?

 

now the second one goes to an injector. you want to visit international for these part$$$ i can assure you of that. good luck

 

Mine's the later style with one plug per cylinder head. Shouldn't be that different. Remove the valve covers and replace the wiring harness's and valve covers themselves to get a nice new contact on the pass through. I recommend replacing the connectors in the outer plugs, but I can't help you with the part numbers, don't know them.

 

Just got back from the dealership, international doesn't stock any of the parts needed so i went to an international/ford dealer and he had them. 37 for the 4 plugs with the tool and 28 for the harness under the cover, they didn't have any of the new pins though. I'm going to install these now so i can drive the truck, need it this weekend, and then on monday order the pins and replace them next weekend. Looks like it should be too bad of a job.

 

well wont be driving the truck anyway, the one pin is destroyed and the 3 next to it look alittle toasty too. So won't be using the truck till wednesday unless someone else stocks the parts locally.

 

Does anyone know the ford part number for the pin with 6" wire on it? International dealer doesnt have it and good luck getting a ford parts guy to even know what it is.
