Properly Testing Vacuum Leaks on Car
high idle concern. I wanted to smoke test this cold before doing any other testing. Idle was at 1300 rpm when it came in. Does it matter where or how you smoke test for vacuum leaks on car? We want to see ANY potential leak after the MAF sensor. Don't think you aree going to find these leaks with a cigar like some clowns say. Vacuum leaks can be difficult and well hidden at times, so smoking them is one of the vest ways to uncover the location. Don't forget to leave a like and subscribe!
