In my efforts to get our coach running right again, I'm narrowing down issues. I used to hear a rapid tin sounding clicking when I opened the fuel access door on my 9 when it was running. Don't hear it anymore and wonder if my coach is starved for fuel exhibiting low
Power and smoking occasionally with bouts of good power and no smoke

Scott,
I don't think so, but will let a couple more people weight in on this.

Did some more research this morning and figured out indeed it does not. So, here I am now coming to the conclusion that I might have sludge in the bottom f my tank. Bryce (BK) had this problem in one of his Setras and had to clean out his tank. I'm hoping to rinse mine with kerosene and open the drain with the coaching heavily listing on the curb side to drain and flush. I don't want to have to remove my tank since I have an aux. pain in the neck.

Scott if you want to do it right you need to remove the tank!
On a second note if you do in fact have the factory "aux" tank that mounts to the back wall of the front bay there is a better way to drain than to "lean the bus to the side."
IIRC the main tank & "aux" both have fittings in the center of the tanks where the hoses hook up.
If this is correct take the hoses loose and find a suitable plug for the main tank.
Then put your solvent (B100 or whatever you choose{FWI-we used parts & brake cleaner) pick the bus up shake it all around to slosh the solvent around.
Oh wait now you may see why it's best to take the tank out! (it's easier to shake & slosh the tank than the whole bus.)
But actually you can drain it directly out of the fittings for the aux tank!
I know it's a lot of work to take the tank out but you can do it right this time or you can keep doing it over and over until you get it right.

;D BK ;D
BK,
I never responded to this....it got lost. I did use the B100 and I could look into the tank and saw that after driving around with the straight B100 for a few hours it cleaned things out really nicely. Also blew out the entire fuel line system from the filters on back to the tank. I'm 100% sure the tank isn't clogged or lines clogged at this point. Something else is going on. I'm chasing it down in another thread... thanks for the advice...you've done the whole remove the tank and flush it thing so you would know :)
I read this and the thing I took away was "drove around with the B100 for a few hours..." If you cleaned your tank by putting aggressive solvent fuel in and drove around, all the crap went into your engine. I don't think you have a leg to stand on, you have a screwed up injection system. I'd start looking on-line for new injectors, and toss the ones you have now, if that's what you did. All new injectors, $1,000. Run the rack, if you don't know how to do it yourself, another $1,000. That's poor Econ 101 to me, to burn used engine oil. Fuel filters can only do so much...
On second thought, you only have 6 cylinders, so maybe $1500 total.
Edit - what HHKen said in the other thread - the tolerances in the injectors are measured with tools I don't own, and I own tenth's reading micrometers...

Thanks Brian, I'm hoping I haven't grenaded the injectors just yet. When running down the road I don't have any smoke at all. Most have agreed that a messed up injector would cause smoke issues. I have none at all...even at full throttle. It's weird. I'm getting the tach and taking RPM measurements tomorrow if I can. I'll report back in the other thread to keep things clean and organized. Thanks for hanging in on this one for me. I know I may have done something gutsy and stupid, now I just need some help figuring out just what it's done.
