It is slow on response either the air gap setting on the governor or the starting aid on the injectors is off JMO hard to diagnose with out having hands on

Ok. As for someone who said something about a blocked muffler, I have a new one on the coach and actually had been running without one at all and still the low power situation exists. So Cliff, it sounds slow to you? This is a good data point for Scott Crosby who is going to be helping me fix this issue hopefully. He's been super willing. He's in Avon, Indiana and I'm crossing my fingers we can connect and get his hands and eyes and ears on our coach. 20 mph in on the shoulder of the road trying to climb little Michigan hills isn't my idea of fun.

It could be time for a new set of injectors after the waste engine oil  ::) the 92 series have spring loaded fuel rods even if the rack is stuck on one injector they still rev up , shut down and sound good but no power 

If you need a set of injectors buy from Don @ Quality Injectors in Oakdale Ca he is old school one of the few left that will do the high,medium and low calibrations on the old injectors 209-863-8810 and his prices are good fwiw I been dealing with him for years 

good luck

I thought governor gap only affected idle, but it affects a lot more including possibly a low power condition.  I couldn't find where the starting aid could affect power output though.  It's easy to pull the valve covers off, put the rack in full power with the speed control lever and see if one of the injectors is sticking or not going to full power.  My memory is trying to tell me that the spring loaded fingers are sprung so that they let the rest of the injectors go to no-fuel if one sticks open, not let one injector stay closed when the rest go open to full power but I can't remember.  Dang, I am fed up with winter, I came so close to going out to the shed to take a valve cover off and look when I remembered that we currently are in a blizzard and have about 6" of fresh snow and blowing a gale...

GOVERNOR GAP
A properly adjusted governor gap will accomplish the following:
Provide sufficient weight travel in the idle range to prevent stalling during deceleration. A tight gap reduces weight travel in the idle range
Provide enough weight travel in the high speed Control range to prevent engine over-speed with light loads at full throttle. A loose gap reduces weight travel in the high speed range.
Prevent the force generated by the low speed weights (double weight governors) from depressing the high speed Springs If the gap is too tight, the force of the heavy idle weights operating on the high speed spring will cause the high speed spring to depress at too low a speed, resulting in low power

Lol I guess I am one of the few left around that times the injectors,sets the air gap and the starting aid and go from there my starting aid gauges do get a work out on the #2 cylinder on the right bank ::)

When I installed those injectors I got from you I did the exact same thing.  Checked all the valves, timed the injectors, set all the rack fingers, checked the gap (it was fine), reset the starting aid and throttle delay and after it was running reset the buffer.  Takes a long time crawling up inside a 5C, wearing my little helmet (I have a 1/4" haircut and cut my head on stuff inside that engine compartment all the time).  The first time you do it (learning from books, no one to show you) takes a long time, the second time you do it you feel semi-competent, the third time you fly, and when you do it the fourth time two years later it's just like the first time...   ;D

Scott I'm 10 miles south of Avon, let me know when you are heading this way and I can take you to Easide welding in Lawrence. They are the best in the business for that type of work in this area. Don't let the name scare you, he's been working on Detriots   since the  60's.   317-823 4055 is the number.

Thanks a bunch steve. And Cliff, you may just be right. I'll find out soon enough. I did admit to Scott that I had used motor oil/diesel mix so he has full disclosure. If that ends up being the issue, I'll be in touch about injectors. I'm stalled until I get some pointed help from Scott or some hands on deck. The weather isn't cooperating either...still getting down below freezing at night and low 40's and blowing and rain..snow is forecast too. It's nuts. I'm beginning to hate it up here..
