interesting possibly simple issue

[taka21]

im having some interesting issues
when im driving and on light throttle the car bogs for what appears to be no reason, if i get on it hard there is no issue but on light throttle it bogs and even bogs on idle, i have no idea what could be causing this
all the vac lines are fresh so im fairly sure it isnt that (i could be wrong) cause im also having the dipstick popping out issue as well
i have a boost/vac guage hooked up and im reading just under 20 lbs of vac at idle when its warmed up(this is 2 lbs more than what she is normally sitting at)
im trying to see if anyone can point me in the right direction
i would love to figure out why my dipstick keeps popping out and why the random bogging
any help is really appreciated
Thank you all

Did you mess with your PCV system in any way, like add a catch can

 

[taka21]

yes i did for about a week but i thought it was causing the dipstick issue so i removed it and returned the system to stock, it never had the boging issue when it was in tho

 

[taka21]

is there anything else that it could be????
oh i figured out the bogging issue
that one was caused by a loose connection to the tps vac also droped once it was properly hooked up

only thing left is that dipstick popping out

Could be worn rings...

Leakdown test.

Leakdown test.

I would say it was blow by caused by worn piston rings

Personally I wouldn't say shit till he's performed a few tests but that's just me....

IJ do you still have the link to the vacum chart , the vac gauge is showing me some different numbers than usual.
