intake seal done as well, just forget to wright. when turn on ac it goes up to 600 rpm, but sometime can drop again. When i push i little accelerator idle goes up to 600-650rpm.

i use many scanners like launch, and professionals , no codes

I driving about one week with unplugged vacuum pump, no codes, no affect to brake pedal( it is nice and strong braking). When he ever start working? Because i think he is a problem.

3.6 , 224000kms, no stored codes

Good day everyone! this is the situation: On a warmed-up car, when you stop at a traffic light, the idle speed becomes 500rpm. This is too low, I noticed that when you stand at a traffic light and press the brakes several times in a row, the idle speed becomes higher, but then it drops again to 500rpm. It's been done: Throttle Body Clean, Spark Plugs Changed,Checked with smoke for vacuum leaks, No check engine light and other, PCV Replaced. And another question, when is the vacuum pump turned on? because I turned it off at all, but it did not affect the brakes in any way, I connected it to the battery - it works. thank you all for your help!
