I bought my truck like two months ago, and latley, when I start her up, it idles at really high rpms, like I am gassing it in park, I am not. When I shift out of park the rpms drop, and it sounds like it should. I do not have a tach, so I do not know for sure how high it is revving, but I would say at least 2500rpms.

And also, there is this really bad whining noise coming from my engine, I can really hear it at low speeds, and it gets louder and faster as I accerlerate, I think it might be a belt or...? All my belts seem tight enough, but I am not sure if that is it cause it gets louder and faster as I accerlate...

Any idea what the problems could be?
 
Well , when you did buy the truck , it was cold outside . The choke could be working .

If you were to sit a few minutes and let it warm up , then blip the throttle , the idle should lower .

The whine could be anything with a pulley and bearings on it , may be something else too . You can spray a little lube on one at a time to see if it goes away .
 
It does it every time I drive it, no matter how warm the engine is, its not as bad after a few hours of driving it as it would be after not driving it for 3 days.. but its still idling way too high..

But for the whine, it is also alot louder when I am turning, like a U-turn I can really hear it.
 
it might be your power steering check if its leaking and also check if your power steering fluid is low. lube your carb linkage and check the cable could be sticking???
 
Hmmm.. I just noticed my breather hose was not hooked up tight, think that was the problem? My mom has my keys cause she has my car, so I cannot start it up right now.. I lubed up everything I could think of..
 
After the first year , you will have hose clamps on anything big enough to use them on .

I always forget about vacuum leaks , its been so long since I had one :doah:
 
Take a can of carb cleaner and spray down all vacume lines and the base of the carb. Also spra all around the intake manifold. If the engine idles up when your spraying,,,, you got a leak.
 
Actually, if it's leaking bad enough to whistle, you can just run your finger around all the gaskets and see when it changed pitch. That's how I found a leaking carb base gasket on my '80.
Plus, it gets your hands in there and your eyes closer, so there's a better chance you'll see any missing/cracked/disconnected hoses.
 
Alright, well I worked on my truck all morning, I need a new vaccum advance for my distributor, and somehow, I leaked out all my PS fluid, I found where it was leakign and fixed it. Its all better now.
