You know, it would be really cool if we all pitched in, in an effort to thank EVERYONE on here who helps out on a regular basis, and bought a FTE community AE lol. Have a thread with whos got it now, and come up with an FTE mascot to send around the country with it, and post up pictures with the mascot on peoples rigs haha!!

 

That's not too bad of an idea at all. I thought of doing something similar, in terms of a tool collection. I planned on zf5 rebuild tools, injector tools (sleeve tools etc. It never really seemed to catch on.

 

Thats not a bad idea a'tall. Only thing i see having a problem with is keeping track of where its at and who has it. And figuring out who we could loan it too....the regulars here id trust giving them my keys lol! (Except Talyn...he has a way of parking in ditches ) But then again it'd be hard to say no to someone who needs help just because we dont know them that well.

 

I have thought for a while that this would be a good idea. I have the ZF5 rebuild tool kit to add to the collection. It seems to me that the best way to structure something like that would be to have the person who is borrowing the tool pay a deposit (it would be pretty easy to do through Paypal) and then have them send the tool back for inspection and then refund their deposit. I would be more than happy to help run the program and I can ship things really cheap at work through FedEx. I have to think about the process a little more to make sure I still think it is a good idea though. I'm not on my second cup of coffee yet.

Bill, The fact that your ICP is that much lower at idle when it is warm, and that is when it runs bad seems suspect to me. I will admit that I don't know enough about what the IPR D/C should be though, so I don't know if it is more likely to be a HPOP issue or what. I guess we need to see what someone with more experience in that regard thinks.

 

MY truck runs 12-13 IPRDC% & 650 ICP at idle . The lower number (580)is not a concern .

Bill, can you post up a summary , the thread is too long to keep re reading it ..

 

The idle problem started several months ago, but was not real bad. It didn't surge then, but it started as a very slight lope, for lack of a better term. It progressively got worse, and then came the surge, but only after the truck has been run and up to temp. I did injector o-rings, glow plugs and UVCHs back in June. I started driving the truck in may and noticed fuel in the valley after driving it every day, so I replaced the fuel pump, hoses and all the o-rings in the fpr and fuel bowl. That's when I noticed the UVCH plug for #5 and #7 was smoking and had oil coming through it. I replaced the UVCHs and went ahead and did the injector o-rings and GPs then while I was in there. There was not an issue with either the GPs or o-rings, but I had new ones on the bench, so I replaced them.
I changed the CPS a short while back with a new IH one. Some time back around the first of last month, while driving on the four lane at 65 mph, it just started missing real bad and lost power. I now know it was the driver's side bank shutting down. It has done this a total of three times up to now. When it does this I can unplug both driver's side UVCH plugs with no affect on how it runs, so I know the whole bank is not firing. When I start the truck cold, it smokes a bluish smoke that will burn your eyes if you stand beside the truck. As the truck warms up, the smoke is not as bad, but you can still smell that eye burning smell. Right before the driver's side shuts down, the rough idle gets real bad and if I rev it to 2500 rpm, it sputters real bad at about 2250 and will smoke like a freight train. Once the driver's side shuts down, I can rev it with almost no smoke at all. The second time that bank shut down I was trying to get it home and drove it about 8 or 9 miles like that. About 2 miles from home, it cleared up and took off running on all 8 the rest of the way. I have never gotten a CEL and there no codes. I have replaced the driver's side UVCH and gasket, the IPR, Injector o-rings on the driver's side, swapped injector solenoids one at a time, tightened the poppet screws, and I can easily get a .003 feeler gauge under any of the armature plates. HPOP res. stays full all the time.
I drove the truck to work today, and it's the same as always. The more you drive it, the worse it runs, and today while following a slow vehicle up a hill, and kinda lugging in 5th gear it stumbled real bad for a couple seconds like it was getting ready to drop the one bank again, but cleared up. It was still missing at certain rpms though.
I hope I covered it all Rick, if not, tell me what else you need to know.

 

Did you try another IDM ? When you do a buzz test , it should give you codes that are stored in the IDM ...Have you looked at the connection to the IDM for corrosion .. Have you checked it for water intrusion . Do you have access to a spare PCM ?....

 

That's a good write up summary. Scrath my last post, I don't see how it could be compression with all that going on. It wouldn't hurt to do it though. I just read that but you didn't change out the PCM, have you?

 

He changed out the IDM from his parts truck.

 

Usually temp related is oil . But I don't suspect it in this case . Warm oil never cools temporarily ...

Get the IDM codes from the buzz test ...

 

Sorry I had to cut out on you, my daughter-in-law shot a deer with her bow and I went to help track and recover it......her first bow kill!!!

I took the IDM from my parts truck and just set it in there and plugged it up and ran the truck for a few minutes to see if it would have any effect on the rough/surging idle, it did not, so I took it right back out. I didn't take my IDM out and check it for water, but I will. I do have a couple PCMs for auto trans, but that shouldn't matter other than maybe getting the "romp" when it starts right? I buzzed the injectors as soon as I pulled in the driveway this evening, no IDM codes. I did a cold buzz test last night, no IDM codes. The scangauge should get the codes from the IDM shouldn't it. It was idling pretty rough when I got home this evening, so I did the buzz test first, then tried to do a CCT, and I got a P1531 code and it wouldn't do the test. The code was for fuel peddle movement. I wasn't touching the peddle, and this evening when we were coming back from recovering the deer, I pushed the peddle, and nothing. Let it up and pushed again and it was fine. I'm going to change the IVS tomorrow evening, I have new ones. The TPS that's in it now is from the parts truck, I changed it a couple weeks ago as a sot in the dark. I'll put the original one back in.

 

Did you check the voltage at the tps? Vref,neg,signal?

 

No, I haven't done anything to it yet. I stuck the one out of my parts truck in it a while back, just to see if it made any difference in anything. I'll check the voltage when I put the original back in and change the IVS.

 

Hmm,I hope the two have something to do with it.the cc needs some lovin!

 

At what point in this sequence did you try the other IDM? I am wondering if you have two issues that were coinciding and masking eachother. I was thinking you said that either the IPR or the ICP was replaced and helped with part of the problem. I'm wondering if that was before or after the IDM was swapped. You might try installing the IDM (bolting it to the fender) and see if that makes a difference. If the ground in the harness is so-so having it grounded to the fender could help.
