Do any of you have any idea what could be wrong with this unit.

This week as we were leaving NC after a two month stay, our Holiday Rambler Vacationer with Ford 6.8 V-10 seemed to have a power problem. 15 miles into our trip,we lost all power. At 10 mph, the fastest we could go, we limped into a shopping center where we called a tow truck and got towed to a Ford dealer. My husband is a mechanic of many years, but this problem is mystifying. At first he and the mechanics at the repair facility were sure it was a fuel pump, but after checking with diagnostic computers, they found computers couldn't diagnose the problem even after following technical steps advised by Ford. In the diagnostic process, they also changed the fuel filter and did some adjustments which they thought might help -- they didn't. In the road test, the mechanic had a fuel gauge attached and we never lost fuel pressure, so they decided it couldn't be the fuel pump. Finally, the mechanics decided it might be a bad Powertrain Controller Module. The part is on order from the factory, and we're sitting here waiting and hoping that it will be the correct fix.

Luckily, we were able to pack up our cats and go back to our son's place rather than stay at the repair shop. While we wait, we're wondering if anyone has had similar problems, and what the fix turned out to be.

Thanks!

Not really enough info about the problem to offer any guesses as to what might be wrong. Keep us updated on what they find!

 

I'll take a educated guess at it. Need the yr of the coach/engine!
Egr not working properly.
Did it Idle correctly?
Something make a nest in the intake/airfilter was there alot of black smoke from tail pipe?
Had the motorhome been run while sitting for 2 months?
A pcm could be the problem,but they usually just die altogether.
Did something happen to the exhaust clogged or severely kinked pipe!
A damged cht(cylinder head temp) sensor will cause a limp home mode ,but they should have picked that up with there diags.
Yes let us know what they find.

Okay - my turn:
Bad gas
Dirt Dauber nest in tailpipe
Fire ants on the MAS

 

I had a similar problem, drove all the way from verginia to new hampshier going 10 mph up hills, I was able to get it up to somewhat of road speed on a long straight away, or down hill, Ended up being a fuel pump, 250 dollars later I was back in business. Not what you wanted to hear, sorry, Other than that, maybe bad fuel???? Mine went out gradually, started out only up hills, I could shut it off and let it sit a while and it wold be fine for a while, But just got worse, till nothing helped.
Very frustrating, Good luck with everything.

 

Could be lots of things, but they'd have codes set for them. Did the check engine light ever come on?

Or is the O/D off light blinking?

It very well might be the PCM if they can't see anything else wrong. It sounds like it's just not figuring out you have your foot on the pedal.

Which could mean the MAF too, but that would throw a code, no?

These V10's with OBD-I (not -II), they don't check parameters for lots of sensors, so no check-engine light or any codes stored. This can be a headache for someone like a ford dealer mechanic who assumes the computer will tell them which part is bad.

Could very well be a leaf or something got past the air filter and is hanging on the MAF. Quite a few people have reported that happening and never figuring out the problem for a long time.

 

"All cars and light trucks built and sold in the United States after January 1, 1996 were required to be OBD II equipped. In general, this means all 1996 model year cars and light trucks are compliant, even if built in late 1995."

SOURCE = http://www.obdii.com/connector.html

 

NOT SO - my 2001 V10 specifically states under the hood "Conforms to ULEV standards for HEAVY-DUTY TRUCK ENGINES".

It's not a "light truck" engine.

It's NOT an OBD-II compliant platform. If I check the computer with my Autotap, it says OBD-I. My 4.6L's say OBD-II.

I read Ford's specs, someone posted a link (Fredvon4?) to, that specifically stated certain things are NOT checked in the "OBD-I" heavy-duty truck engines, meaning the 6.8.

There is no cat efficiency test, because there's no O2 sensor after the cat - which means it already violates OBD-II. There's no O2 sensor heater test, etc.

I just had the thing emissions tested - they plug into the computer now and don't even bother with the sniffer test anymore. It failed the first time around because it didn't complete the Cat and O2 heater monitors. OBD-I.

 

Well I just checked the the Escapees site and they installed a new PCM and it didn't cure the problem. They never checked the sensors so its my understanding that is what they are doing now. I think its getting to the point that if they can't find a code they just don' look any further.

Denny, you got THAT right!

Especially with the V10's that are not fully OBD-II. They don't log codes for lots of things. Even the MAF.

Completely unplug the MAF and see if you get a check-engine light.

I didn't

That's one of those things that are not checked for ...

 

Denny, your probably right. If they can't find it through the plug and play their lost and it becomes a R&R guessing game.

 

Check The Catalytic Converter. Have A 2003 F 350 Cc V10 Drw 4x4 That Lost Power Pulling 32 Ft Gooseneck And Lost Power. Limped In To Ford Dealer At 15mph And Found That The Converter Was Causing The Problem. Covered Under Warranty No Problems Since Then.

 

To give you a good example we have a 01 Alero that we bought new. I have never serviced this thing it was always done by Mr Goodwrench. We started having trouble with it starting, backfiring and poor gas mileage. They read codes and reprogrammed the thing at least 3 times with no success. So one day I was in the garage I looked under the hood (I hate the motors that set in there the wrong way) just for the H of it I checked the air filter, plugged tight, new filter and its back to 30 MPG and starts great. I can't get the thing on my ramps so I now have a friend that owns a garage/body shop service the thing. Yes I own a GM car but the thing get great mileage and with a 3.4 V6 it will turn the 225/50/16 Goodyear Eagle over, maybe thats why Jami doesn't like me driving it .

OOPS! I would like to take the last part of your signature and add it to mine now.

 

What yr engine? That will eliminate alot of things left un turned!
