Ok I have a 2007 Ram 1500 with the 4.7L engine 2wd quad cab and when checking vacuum my gauge reads a pretty steady 19 but when rev the rpm’s to 2500 and let go the gauge goes to 23 then slowly drops back down to 19 but it takes at least a minute to drop back down is this saying my exhaust is clogged somewhere or should I only pay attention to the fact it stays at a steady 19 when it’s at idle? I’m just tripping on the fact that when revved to 2500 it doesn’t drop to around zero then jump back a little high for a second then drop back to 19 where it started like my book says it should?
