    your power brakes work on vaccum from your engine so when you are running at a high idle your have more vaccum to your power booster so the brakes could feel a little softer

I have a 1998 Toyota caldina gt and lately while idling it starts reving up and down on its own. I also noticed today that after driving I pulled up my drive and put on the brakes which seemed tighter and...

If the brakes feel " Tight" then there is a fault with the brake servo/booster. Get a tech to check the hose and connections of the servo because any split in the servo/booster hose will affect the intake manifold vacuum and cause poor running. Fix the servo line and it will probably fix the main problem as well. May only be a clip want tightening. Get a knowledgeable person to help if you are not sure yourself.

Over reving

Can be a number of things (check all of these):

  1. Stuck throttle linkage or accelerator pedal;
  2. Loose butterfly on throttle body;
  3. Stuck or malfunctioning idle air controller;
  4. Loose or damaged throttle body or bad throttle body gasket;
  5. Cracked intake manifold or bad intake manifold gasket;
  6. Bad ignition control module.

I am having serious problems with the idle modual it reves at the norm then all of a sudden the reves just increase up to roughly 2.300 and then come down to near stalling

First Check All Air hoses. Make sure no vacuum leak are present.
make sure your ignition coil are good. This will make engine idle roughly. For the rpm to high or to low maybe your air idler is no good. If you're car turn off it might be overheated. Check coolant level. Make your not mixing water with oil. Check the oil dipstick to verify. If like a milky color then it's mixing water with oil. This will car to stall and run roughly
