AFAIK it can't be overfilled, it just drains to the crankcase. Sounds like it started right after the oil change; what oil & filter did you use and what was previously used?

 

A faulty cam position sensor could possibly do this too. They can be working and be just a little 'off' to where they cause goofy problems. It's good to keep a spare on hand anyway so replacing it isn't money wasted since the old one can be kept as a back-up.

 

This is a strange problem and I hope you find the solution soon and post up what finally fixed it.

If you get a CPS on the recommendation of '88 E-350, stick with Ford or International only.

 

I highly suggest getting a something for your phone or other mobile device to tap into the trucks sensors. It would make this a lot easier for you. If you have Android, torque pro is a good app.

Just my two cents worth on that

Mine stalled on me once but with it rolling, it popped back on. This was exiting the freeway. Never did show its face ripn around town. Just, now i think about it, exiting freeways after being in a high speed issue and tryn to come down in speed quickly..aka, throwing in N or deoress clutch to grab gear. Its when you can here, feel and see RPMs drop lllooooowwww

 

I have been having the exact same problem with my e99, but my is an auto so no popping the clutch. It has progressed to the point of occasionally leaving me stranded. I have changed the IPR, ICP, 2 CPS, lpop, injectors, and tps. None helped. I scan mine and it's usually an IPR code and when it dies it struggles to build ICP. I hope someone can help with this because I've spent a lot of money and time and not found the problem

 

Updating my issue.......
So somewhere around the middle of June, I changed my fuel filter thinking maybe that was the issue. It was not. Still had issue. Two days ago the gasket on the new fuel filter blew out ,bathing engine compartment and under carriage in diesel. Not sure why it took a month to fail , but it chose to do so 35 miles from home. I tried to get it to re-seat but we all know how that went. Hell.....sometimes it's difficult to get a new one to properly seat. Anyway called a buddy who brought me a new filter and I was up and running in no time.
So for 30 of the 35 mile drive home was uneventful......no stalls or drops on rpms. I started to think maybe the gasket was slowly leaking before it blew , therefore bleeding off fuel pressure ???? The last 5 miles or so made me scrap that thought! Stalled at 2 red lights, and almost stalled at 2 others. Scratching my head again! The more I deal with this issue, I'm beginning to believe and narrow it down to temperature. It absolutely WILL NOT do it in the a.m., regardless of air temp. On the evening drive home,,however, is a whole different ballgame. Seems as though when the air temp rises into the 80's and 90's , it's guaranteed to happen. In my mind it's got to be something temp related but I'm lost at what it could be. Truck runs absolutely great the rest of the time and this is what really stumps me.....I would think if my low rpm /stalling issue is being caused by a specific part, wouldn't that part failure cause a noticeable decrease in engine performance at all other times?

 

I spoke with a diesel mechanic in my area this morning and he said the issue is most likely the hpop. for me at least, and our issues sound identical. I ordered a hpop rebuild kit this morning, should be here in a couple days. i'll let you know if it fixes the problem.

 

I would hate for that to be my issue since I am on my second t500 from joey @ terminator. 1st one died just out of his warranty period and he graciously honored the warranty and replaced it free of charge. Current hpop is only a year or so in service so I hope thats not the issue.
Just don't wanna have my truck down as it's livelyhood.
What does the rebuild kit include? I assume hpop removal is necessary for rebuild?

 

Keep us posted fellas. I hope you guys figure it out soon and the downtime is not too much of a pain.

 

I had the same thing happening to mine for awhile, minus the stalling. It ended up going away when I swapped out IPRs early last year.

 

I know everyones thinking it but....whats there to rebuild in the hpop besides sending it out to a qualified company that builds them up. Not sure what "kit" your talking about..hopefully the screen inside has evidence of something

this is what I ordered

 

Sorry brother, but all i see are a bunch of orings and an extrnded service plug. If it ainta leak'n, it ainta problem

 

Anyone following this thread have a known good spare HPOP they could lend or receive a deposit for in order for either of these gentlemen to install and see if that is their problem?

I know it is a long shot, but I have seen things like this happen before.
