how much will a vacuum leak cause the reading to change. i think i may have a leak but it is only reading 2 or 3 lbs higher then normal. my car is usually around 20 now its around 17 or 18. what do most of our cars average for their vacuum pressure and is this a big enough change to be a major problem?
i've been throwing a code for misfiring so im trying to figure it out.
any help would be great. thanks
