From one of my post earlier, one of the suggestions was to check for vacuum leaks. What is the best method for this? Any help would be great.[&:]

Propane torch......not lit obviously. Honestly, its a pain in the **** without a smoke machine or PID capability. The BEST thing you can do is monitor your oxygen sensor voltage while spraying propane or ether around the engine compartment. When you see the voltage go up, you are spraying the area of the leak. You may hear a change in the way the engine runs as well, but the o2 sensor thing is 100% accurate and ideal. Know anyone with one of those fog machines? Rig it to spray through your brake booster line and tape off the throttle body and tailpipe. Eventually the smoke will begin to leak out of the intake at your vac leak location(s) but you may want to consider a good hose down with intake cleaner afterward. I don't know if the non-toxic chemical used to generate the smoke will harm anything. I SERIOUSLY doubt it will though.

the smoke used in smoke machines is safe for intake leak testing. capping off the exhaust isn't necessary. you can also use carb cleaner. spray slowly over lines and gasket area's, car will surge or rev when your near the leak

You can also use a small peice of rubber tubing and hold it up to your ear and listen closely for the leak....This method wors sometimes, just dont get it too close or it might hurt the ear a bit
