vaccum leak?

Any brake related products are not to be burned in a motor. If you look on cans, and cleaners, you'll see it says, " safe for 02 sensors " like on fuel injector cleaner etc. etc.. there is a reason for that. it leaves residues that damage the sensors. unless its TBI cleaner, you should never burn them in a EFI car or anything with 02 sensors, or intake sensors etc. Thats a general rule with all cleaners. like you shouldn't use gum out on a efi car etc.
