[QUOTE="wmadoty, post: 1042310, member: 27157"] I quit using flamable substances to check for leaks years ago, several bad experiences in the shop. Now I use a spray bottle filled with water on mist. Surprisingly, if the leak is small you will still see an idle increase when you hit the spot with the water. Most of the time when you find the leak you will experience the opposite, the engine will slow or even die. If the leak is only on one cylinder, you should be able to see a difference on spark plug deposits. Spray the coil packs and wires with some watter as well and listen for arcing. I have seen a weak spark condition look a like like a vac leak. [/QUOTE]
