<p>I'm not sure if you've worked your problem out yet, but I've heard of similar symptoms before. A friend of mine has a 72 Bus with dual webers. He rebuilt the engine and had the trans done at the same time the engine was out. He installed everything and started driving it. After around a month of cruising about, he started noticing an odd problem that sounds exactly like yours. When first driving the bus, it worked fine, but after warming up a bit, he'd lose power and if he let off the…</p>
<p>I'm not sure if you've worked your problem out yet, but I've heard of similar symptoms before. A friend of mine has a 72 Bus with dual webers. He rebuilt the engine and had the trans done at the same time the engine was out. He installed everything and started driving it. After around a month of cruising about, he started noticing an odd problem that sounds exactly like yours. When first driving the bus, it worked fine, but after warming up a bit, he'd lose power and if he let off the clutch (even out of gear) it would die.</p>
<p> </p>
<p>He'd been told by the place that built his trans that it was likely the needle bearing in the crank or the throw out bearing (I forget which...some bearing in there) so he replaced it and found he still had the same issue. He now thinks it's the transmission. That the input shaft is somehow not disconnecting from the internal gearing the way it should, and the trans guy he used agrees. But at this point he's too lazy to pull the engine again and just keeps using his other (aircooled) car.</p>

<p>I'd be curious to hear if you've resolved it.</p> Thanks Mitch. I hereby solemn…tag:vwcamperfamily.ning.com,2011-08-30:4450389:Comment:468252011-08-30T15:31:51.464ZJeremy Nixhttp://vwcamperfamily.ning.com/profile/JeremyNix

<p>As the owner of a fuelie, you're gonna have to learn it inside and out, eventually. Promise me that, at your darkest moments of despair when the damn thing just. won't. work. right, that you'll never (ever!) consider scrapping the fuel injection for aftermarket carbs (ugh) or, god help you, a single centermount carburetor.</p>
<p>Please.</p>

That is really exactly what it felt like. One thing is obvious, I need to get the gas gauge fixed! I think I saw a blog post from Ludwig about removing and cleaning the gas tank in a bus! I'll probably refer to that this winter! I'm also not leaving town Wednesday until I have the names and addresses of every VW shop along the way. Just in case! Plus I'll have my John Muir book, and my Ipod filled with all these great forum threads of what to look for and how to check it. I think I can…

I have reread your original post again and now believe that your sluggish issue was due to you running the bus out of gas (or just about out). A couple of responses above state tank debris being the possible culprit (probably correct). Run the tank that low and the debris collects at the tank drain and inhibits the gas from flowing.

I'll do that. I have a feeling that eventually I am going to have to deal with a problem with the fuel injection anyway. I think I remember reading somewhere that it has it's flaws. Thanks for all this valuable information guys.

You can. Remove the hose that is connected between the vacuum can located on the distributor and the throttle body at the throttle body. Remove the distributor cap. Suck on the end of the hose (should still be connected to the distributor) and you should see the points plate move when you pull a vacuum (suck) on the hose. You should be able to hold it in place with constant vacuum. However, with fuel injection, many things could give it a sluggish condition such as ignition system…

You should be able to hold it in place with constant vacuum. However, with fuel injection, many things could give it a sluggish condition such as ignition system condition, fuel tank condition, or intake air conditions not to mention condition of the fuel injection system itself.

So I take it you have fuel injection based on the picture. The other pictures you are seeing may be of carburetor engines. Anyway, I wonder if your vac advance is getting stuck or gummed up or something to where it is not moving as it should. This would create a sluggish condition but still run.

<p>Yes I miss spoke the color should be a blue- white nor yellow or green . you could also look at the wires in the dark and see if they are leaking voltage or if the ends are corroded.</p>
