Ok 07 Ram 1500 2wd 4.7L quad cab with about 175,000 miles it runs strong. I bought it used it has a couple leaks like valve covers and oil pan not bad just slight leak anyways sometimes it feels like it might be a little sluggish not sure really cause it gets after it pretty good. So I put a vacuum gauge on it and it’s pretty steady at 19 (I’m about 1600 feet above sea level) but when I rev it up to 2500 rpm’s and let go of the gas real quick it jumps to almost 24 and then drops slowly back to 19 it takes it about 1 minute to go back to 19 is this telling me there’s a clogged pcv or maybe a clogged exhaust or is it good and I’m tripping. The reason I ask is I was told when revved to 2500 real quick that it should go to almost 0 then when let go of gas the vacuum should jump a little higher than from where it started then drop back to starting point which is 19. Any help will be greatly appreciated thanks in advance and sorry so long

 

That sounds pretty normal to me.
