but I will tri and fint the leak. somehow

Okay to find the vacuum leak, get a can of throttle body intake cleaner. Start the car and spray the can into areas like around the intake manifold gaskets, the throttle body gasket, the various vacuum hoses around the manifold. As you spray pay attention to the idle of the car. If it gets worse as you spray the can in a particular area then you've got a leak around there. Also you will notice the fluid being sucked in and not just running off.

Here's some other check points:
Is your car stock? Do you have an aftermarket intake? If so make sure all your hoses are connected properly. Check your MAF. Clean the sensor with some rubbing alcohol and a Q-tip.
Check your air filter for dirt build up. A badly clogged air filter can cause some problems. Maybe you go a dirt clod or rock stuck in there....trust me it can happen.
Are your spark plugs & wires new? Check to make sure your spark plugs are installed correctly (tightened properly) and that your wires are hooked up properly, ie. make sure Cyl. 1 wire is connected to port 1 on the dist cap etc.
I had an erratic idle when I first got my 96' and it turned out to be the upper intake manifold gaskets. Dealer replaced them and no more problems. If that's where your having a problem good luck those things are a PITA to change out in your garage.

Good luck.
