    check vac lines, especially to the brake booster. test/replace the inline check valve to the booster & make sure it's in the correct way.

    edit - I own a MX-3, they are notorious for rpms dropping & lights dimming because you push the brake. lol this is the common answer for them

        is there any easy way to check vac leak beside just looking at the hoses? not just brake and turning wheel will drop my rpm, especially with the lights on and the a/c kick in, it made it worst.

          If you have one of the small propane tanks with a nozzel on it (like used for plumbing), you can just crack the valve so that propane is coming out and then move it through your engine bay, going over all the hoses, with the engine at idle. If you hear the engine pick up any, it is from the propane, which means you have a vacuum leak.

            check your air boost valve. it's suposed to keep your idle steady when stuff is turned on like A/C.

              ok i found there a few of the vac hoses to tb is cracked, so i replaced them, but it didn't fix the problem, where is the air boost valve and how to check it? is it #7 at that pic? my rpm is fine it stays at 800 when stop, but i noticed that when i turn the steering wheel when the car at full stop, it wil drop the rpm, also when i closed the power window all the way up, it also drop the rpm, then when i let go the window switch it will go back to 800, i dont get it. the battery is new and the alternator is fine.

                Sounds like normal to me. Everyone's RPM drops when they turn the wheel (the power steering pump is a hydraulic pump, and making it work loads the engine). Same thing with the windows, you are drawing electricity, which loads the alternator, which loads the engine.

                How far does it drop? 100-200 RPM isn't a big deal.
