Cruise Control Driving Me Crazy!
OK, heres the story. For a while now, the cruize in my pickup has been acting up. It works, but will slowly accelerate the engine when it is turned on, and it accelerates hard when rolling downhill after a climb that put a good load on the engine(if you all can understand that ). Thinking that this may be the servo, I bought a used one that worked according to the owner. I installed the servo, and it did the same thing. This is starting to get on my nerves!
So, what do y'all think that I should take a look at. Could it be the wiring or maybe a speed sensor? Is there a chance that the other servo is also on its way out? Could it just simply be the cable adjustment? I assume it ain't the clock string thing. I am also ruling out a vaccum problem, since the cruize does work.
Thanks for any help!

I hate to say this, but good luck at getting it solved. If you do a search on this cruise control thing as I've done, you will find that you never hear of anyone resolving this problem or anything related with cruise control. A switch change out on the steering wheel, is about all you will see that whas somewhat successful. If you do figure it out, please, let all know!

I had the stock vacuum line break right where the hose goes into the servo. I plugged it with a bolt and have yet to go down to the parts store and buy $1 worth of vacuum hose to replace it. If the vacuum leak it very big, your brakes will get rock hard, yet the vacuum pump will suck the skin off your finger.

Actually, now that you mention it, the brakes are a little more stiff than they should be! Maybe a vacuum leak could be the culprit! How should I check for vacuum leaks? I suppose the propane method will not work with a diesel engine and external vac pump.

Do a visual first. If you don't find anything, get a Mityvac type hand vacuum pump and try to pull a vacuum on the system. Work your way from the pump out until it starts holding a vacuum and you'll find the bad part.

Ok
I have, I will, and I shall in the future.
You do it your way, i'll do it mine, but belittleing someone because you think differently is not the way to go, especially from an administrator.
Probably cant use eather to start a diesel either huh?

Ether works fine to start a diesel - provided you've disabled the glow plugs or intake heater. And your method of finding vacuum leaks works fine - on a gasser.
It's got nothing to do with thinking differently. Your advice was flat out useless, but I was trying to be gentle by making a joke about it.
Diesels don't make any vacuum, the vacuum lines all go to a vacuum pump mounted below the injection pump. Spraying stuff on the vacuum system will just make a mess.
Belittle, then educate.

ROFLMAO. That's a good one. Since 90% of my engine knowledge is diesel related, I was wondering the reason behind the spray in the vacuum line. Now I know.
Actually, since you have cruise issues, I'd do the visual first, starting at the servo. Not hard to catch if the light is good. Pry and flex the lines to see if any are roten, etc.
