My wife and i just spent a little time going over her and coming up with a list (extensive) of repairs and upgrades to do after we resolve the running issue. Its amazing when you "have to have" something how much you overlook when your buying it - now that the adrenaline rush form purchasing has settled you sit back and say my goodness what have we gotten into. lol - I know i can handle it but still its a big project...... To the point of my post... we came inside flipped the tv on and "The Money Pit" was on...... the guys are looking over the railing and say "hey buddy did you really buy this house?" I hope that wasnt a bad sign....lol.

Not to worry, all of these rigs are good at generating lists. The first ones are the most daunting. But you don't have to get it all done right away.

Once you get the running issues sorted and work down the list a bit, you'll come to the point where it's ready to go camping and have some of that sort fun.
Which will only create another list.
But also some big smiles.

As you go along the trips can get longer, smiles get bigger and the lists shorter.

In the mean time what a nice place you have there to keep it and get things sorted out.

Cheers Richard

So I opened up the distributor today. This is what I found..... went ahead and installed a new distributor assy with new cap and rotor. Same result though. I was sure after seeing the inside of this distributor I had found the problem.

Mine looked very similar, rusted to hell and those black deposits.

Sounds sensible. I imagine you have already clocked that you can see the timing marks from underneath the vehicle. It's much easier with two people, one below and one at the doghouse.

Yes timing is next - I was by myself and ran out of time but the job seemed quite hard without a helper.

What is the required fuel pressure for your fuel injected engine?
I'm wondering if the correct fuel pump was installed, you said it is new?
They may have spec the carbed engine.
Stranger things have happened.
Did the PO say that it had been running well?

Maybe check the fuel pressure close to the tank.

Cheers Richard

The shop says it was 13lbs of pressure - spec is 9-13lbs.... I was shining a flashlight in there today - plenty of fuel when it bogs down - if anything maybe too much fuel but no black smoke in the exhaust....

As far as the previous owner - tough to say - he said it was ready for a cross country trip - Ive seen enough to say no way - he loved the rv and I think that blinded him in many ways.....really nice guy...

unfortunately for me - when I first went to look at it (it was priced very high with the caveat it was the best example in existence) I knew right away that it was not worth anywhere near the ask price so I didn't spend a lot of time looking it over (didnt want to waste each others time - he already told me of a low offer that upset him)- some weeks later he came back and asked why i wasn't interested and honest feedback would not hurt his feelings - I was honest about condition/price - he said hit me with an offer - I did - and he accepted - The rest is history....lol... If the coach really has 11K miles and I can get it sorted out I think I got an okay deal - so far Im feeling like I overpaid..... but thats water under the bridge -

It does have 8 new tires - new belts - new hoses - (supposed to have new brakes but I have not gotten that far)

I know exactly how you feel...When I bought my 310 TD, the PO showed me everything that worked, quickly skipped over stuff that sort of worked, and didn't tell me about anything that didn't work.
That being said, I was only concerned with the condition of the body, powertrain, chassis mechanical, and condition of the flooring gridwork; everything else was something I could fix with money, time and effort.
I haven't regretted buying her at all......even though I found this....

I ordered the adaptor. I only had a odb2 reader. I will also have to check the fuel pressure myself as Iím counting on what the shop told me. If you look closely in the video you do see fuel pouring in there though.

Depending on your view, but you might want to eliminate a few potential causes e.g. MAP sensor, IAC valve. Probably cheap fixes and if it doesn't help, you know you have a new unit and a working spare.

I did replace the MAP sensor - I have a throttle position sensor as well - I did not get an IAC valve but will do that as well.

Your video sure sounds like the accelerator pump failing in a
carburator of that era. When the pump didn't work the engine would
stall if you stabbed the gas pedal. But if you accelerated slowly
the engine would run OK.


Since you have a TBI system you probably don't have an accelerator
pump. Is that true? If you accelerate the engine slowly can you
get it to run fast? If so, then your problem must be that you don't
get that extra shot of gas that the engine needs to accelerate.


In a TBI system how does the computer know when to give the
extra shot of gas? Is there a manifold vacuum sensor that

connects to the computer? Is there a temperature sensor that
connects to the computer?

I haven't looked at my throttle body while revving the engine but I'm wondering if you're getting to much fuel which is bogging the engine down?

Unfortunately I'm not in a position where I can start my engine to compare.

To my untrained eye that just looked like an excessive amount of fuel coming out of the injectors.
