Idles good at about 5500 rpm starts missing new plug coil and condenser,carburetor cleaned
SOURCE: Techometer Gauge reading erratic above idling
take the dash out and make sure all the grounds are in good condition and also the grounds around the distributor
SOURCE: New plugs, new fuel filter,
you have a vacume leak explains all symptoms runs leaner better gas milage listen for hiss look for cracked or broken vac lines
SOURCE: engine stalls
The throttle position sensor has a small amount of adjustment in it. The plastic case has a slight slot in it. On the opposite side of the TPS on the air horn you will see a throttle stop with a hard to move screw. You need to get some play on that screw to have slack to adjust the TPS. I think it was good for 100+rpm at base idle.
This may help you, but check you EGR for diaphram and carbon buildup.

When I recently ordered parts from Saber Cycle, they included a piece of information that pertained to my motorcycle, which is also a 1983 Honda Goldwing GL1100 Interstate. Here is what it says, I hope this helps:
Air Cut-Off Valve
The air cut-off valve is an extremely important part of the fuel/air intake system that is frequently missed even my competent mechanics, most of whom are not even aware of its existence or how it functions.
Every GL1000 has one, located in the air intake tube, between the air cleaner box and the manifold. Every GL1100 has four, located in the top air intake passage of each carburetor, and every GL1200 has one located in the plenum box below the air cleaner box similar to the GL1000.
These valves are "air blockers", along with the carburetor o-rings, serving to restrict air flow and increase the fuel/air mixture ratio when the carb slides are in the lower RPM range, up to closed so that the machine will start and idle smoothly with virtually no choking and accelerate rapidly, with no stumble or hesitation.
When typical starting requires heavy and prolonged choking to keep the bike running, when stalling and hesitation occurs even while "warmed up" and when backfiring pops while the throttle is shut off while cruising, most people will start fooling with the air screws to try to overcome the problem, only making it worse along with reducing their gas mileage.
Running with dysfunctional air cut-off valves can causes severe engine damage or failure. When the valves are dysfunctional, the engine pulls nearly total air in the low RPM range through the carbs and on to the combustion chamber. The fuel/air ratio is extremely poor with pre-ignition long before the normal 38 to 40 degree firing point, generating an enormous amount of heat, with no power, which is trapped a longer period of time in the cylinder before the exhaust valve opens.
This heat goes mostly up through the cylinder head, gradually incinerating the head gaskets and allowing engine coolant (anti-freeze) to seep into the engine. You can easily spot when you are in trouble by a puff of bluish-white or white smoke on first starting the engine. Don't leave it alone. Change head gaskets immediately or you could take out your bottom end bearings, ruining the engine.
For those of you installing new exhaust systems, you will discolor your headpipes, either blue (lean state) or gold (rich state). You can destain your pipes using "blueaway" or "blue-off" but be careful not to rub the chrome, just dab gently.k These compounds are usually purchased at a Harley dealer or Harley oriented aftermarket shop.
Honda genuine pipes, like many Yamaha pipes, have a double wall for a portion of the headpipe which masks this discoloration-but also masks a bad state of tune. Even if your pipes are original and still in good shape, don't think that you are OK if the bike has any or all of the dysfunctional air cut-off valve running and performance characteristics.
If your 1975 to 1987 Gold Wing is not getting 50-58 miles per gallon (20-23 KM/Liter), you have one of the most obvious signs of trouble. It is likely your air screws have been backed out to try overcome the effects of the poor running, stumbling, starting and stalling and quitting.
Resynchronize all four carbs to the #3 carb vacuum level using mercury carb sticks or vacuum dial gauges. Stay with strict use of the setting levels in either the Honda, Clymer or Haynes manuals. Do not attempt to tune any other way! Guessing will not work and can cause considerable engine damage!!!
It can be issue
with IAC( idle air control valve) causing the problem.

Car
not starting or turning over indicates towards multiple possibilities. It can
be issue with battery or weak battery. But if battery checks out ok, then it
can be starter issue or faulty alternator or problem with low fuel pressure or
no spark at spark plugs due to dirty spark plugs or faulty ignition
coil or injectors getting cracked or dirty and needs to be cleaned.
To
confirm the problem, the basic troubleshooting is required.

Hi, Bob I would really love to help you with your motorcycle question but due to the magnitude of yesterday's solar flare the batteries in my crystal ball are dead and my mental telepathy headset circuitry was melted. I need the year, make, and model of your motorcycle please click on " Ask For More Information" directly below and provide this information in the box that will open and then click on the green "SEND" box in the bottom right-hand corner. Good luck and have a wonderful day.
Well, as its a carbed bike, the usual cause is an air leak at the carburettor mounting rubbers, either an insecure carb or a cracked rubber.Spray a little easystart around to seecif it speeds up, thats where the leak is.
