RE: IML: sticky throttle

["Brooks Harkey" <vm.dude@xxxxxxxxxxx>]

IF it is a cable -- and I do not know whether it is or isn't on this model
-- one thing that will cause the cable to stick inside the housing is if the
ground strap from the engine to the body is either broken, missing, or not
connected well at one end or the other.

What happens is the electric ground for the body (think radio, lights, all
other body-mounted electrical equipment) has to find a way back to the other
end of that negative battery cable... which is bolted to the block.... and
down a throttle cable or a shift cable is an easy path for it to get there. 

IN the process, it tends to weld the cable to the inside of the housing.

So you might check your ground strap.  That's what it's there for.

I believe that the trottle is cable controlled. The metal cable is 
probably sticking inside the housing. My '65 Imperial is, and has been, 
doing this for years, but only enough to make it idle too fast once in 
a while. The same tap with the foot seems to release it. I think the 
cable should probably be replaced. It may be possible to soak it in 
something to free it up. The housing is synthetic, so be careful what 
you use. Probably, something silicone based would be best. Don't use 
WD-40. It is not a lubricant, but rather a cleaner. You may also see 
some light dirt build up where the cable protrudes from the housing on 
either end, you might try to rub this off with a fine grade of steel 
wool.

Within the last few days I got the '65 Imperial going, and that old 
familiar problem reminded me of itself once again. I got my emergency 
brake cable replaced, new fuel pump, A/C converted to 134A, and it is 
going to the front end shop for some work tomorrow morning. I'll 
probably be working on that cable next, and I'll keep the list posted 
as I go through the steps.

The extra spring was a good idea for a temporary fix, but now that it 
is sticking again, I am quite certain you need to do more.

Hi All,

 

About a month and a 1/2 ago my throttle on the 67 lebaron starting 
sticking , it would remain at whatever was the fastest speed I drove 
at, I had to tap the accelerator HARD to unstick it.. I went and put a 
stronger return spring on it and solved the problem, until last week 
and its doing it again. If I work the accelerator by hand it seems to 
work free. I researched the archives and did a web search on sticky 
throttles but had no luck . any body ever had this problem. thanks, 
mike
