I hope someone can help me with this....
got my engine rebuilt this past summer and the idle was a little rough and I was told that was normal. But it has been almost a year and It is still idling rough. It could be a different problem, could have been the rebuild at first and now its something else. The idle is fine at startup, nice and high as it was set for the rebuild but then it drops down after it cools off but its not a clean drop. It goes dangerously close to stalling then comes back up and then too low again repeatedly. My acceleration is fine but the idle when stopped worries me. I am hearing some high pitched squeeling (NOT THE BELTS) that goes up and down in pitch and loudness with the idle, I was thinking it was some sort of vacume leak that may or may not be realted to the idle. Also I never readjusted the idle after the rebuild because i wanted to wait till it got more even. Could the high idle setting be contributing?
PLEASE please please give me some ideas I dont have a clue as to what is going on. I cant pin point the noise and the idle is a bitch. Also sean you told me that when I turn my steering whell I am putting weight on the engine because something was broken cant remember the name though.
HELP!

You got yerself a vaccume leak allright.
Get Yerself some carb cleaner and spray it around the vaccume lines. Spray a spot and wait a few seconds.. if the engine dies, you found your leak.
If you spray under the LIM and the engine dies, that could be the vaccume spider for the Oil Injectors.. that needs fixed pronto...
If you take a big piece of fuel line, brake hose, vaccume line and stick one end in your ear and start pokin the other end at suspect points, you can also find the source of the squealing that way.

Its always been my experience that a poor idle is due to a vacuum leak (which it sounds like you have) or low voltage (which you may or may not have). Does the voltage dip down before the idle falls really low (below 800)?

My car did this once, but it was because I fried the leading coil. The old "low bouncing idle". It also had no power, but yours sounds fine for power, so it's probably something else.
