This is about my '97. I haven't done anything to try to trouble shoot this yet, been trying to get Tyler's truck going, but here's what it did. We went to pick Tyler's driveshafts up at the driveline shop this afternoon. It's about a 20 mile or so drive. About five miles from the place, on the four lane running about 65, my truck started to miss real bad, shaking the whole truck. It lost power and I had to drop a gear to pull a small hill. Turned off the four lane and on to the road to the shop and limped it the rest of the way there. I stayed in the truck and let it idle long enough for Tyler to go in and pay and get the driveshafts, about 10 minutes or so, never shut it off. We left from there and the truck seemed to run fine until about three miles or so from home. It didn't miss and carry on like it did the first time, but was feeling like it wanted to. Now, keep in mind I have had a rough, surging idle issue for a while now, and for the last few weeks, I'm getting a little vibration around 1600-1700 rpm. I did injector o-rings and UVCHs the end of May or first of June. New CPS from International a couple weeks ago. What are you guys thoughts.

 

I agree with your earlier speculation that it sounds to be IPR related. Does that Edge programmer that Tyler has pull live data? I think if it does I would scan for codes and see with your ICP is running when it is acting funny like that (or when idling, if it is still idling rough).

I'd look at the Valve cover connectors too just for gits and shiggles...

 

I agree with Nate. See if it starts when cold. If so, tell tale sign of ipr o rings.

 

Sounds like uvch, but you said they are new. I'd check to be sure like Nate said.

 

Bill, i just solved this issue today. Ive had rough idle, surging also for a while now. Yesterday, i turned onto my road and it started missing, like i had an entire bank out. Pulled over, and it proceeded to idle at about 4-5 hundred and then up and died. Started it and it ran fine till i got home. Turned it off and back on and i had a bad loping idle. Checked the ICP and there was oil in the plug and coming from around the plug where it goes into the motor. Got one from Ford for 193 bucks, and it solved the issue.

 

I think the Edge will look at live ICP Nate. I haven't messed with it at all. Tyler used it to pull the code from his green truck this evening. I'll try it tomorrow.

It starts and runs great when it's cold Todd. Today is the first time it has missed and lost power like that. If I go to the trouble of pulling the IPR, I think I'm gonna replace it with a new one.

 

How old is your CPS, Bill? That's always a possibility too. Might be an easy thing to try to swap it out if you have another known good one to try.

 

Sounds like mine Rob, but mine didn't die, it kept idling. I checked the ICP a while back and there was no oil. I even took one from one of the other trucks, but no change. That may not have been good either though. I've been trying to save up enough to order a new IPR and ICP from Clay. Might be sooner than I had hoped LOL!!

I will definitely check those tomorrow too Darin. I never let "new" rule out "bad" LOL!! I've seen a ton of new bad parts over the years!

 

I wish I would have known you needed one. I have 3 or 4 of them I could have sold you for less than half that.... One of them is still in the Motorcraft package too.... Oh well, I guess you probably would have needed it quicker than I could have gotten it to you too. At least it was something simple.

 

I just bought two new ones from International a few weeks ago and put one in then Nate.

 

Sure sounds like UVCH

 

I'll take the one in the package Nate! How much?

 

Sounds like IPR or UVCWH issues to me then. I would try and use the Edge to see if you can read ICP or not. That would be an easy place to start.

I'm sure we can work something out for an ICP if you're serious.

 

When I replaced them, I bought them from Napa, so I'm gonna give them a good going over tomorrow. We've been all evening trying to get Tyler's truck fixed, and I haven't even raised the hood on mine. I just hope it gets me to work tomorrow! LOL!! Wife's car is still in the body shop from the deer.

 

What should ICP be?
