When my engine is at idle my vacuum is around -12psi it used to be around 19psi. Should I be worried? Could moving my distributor cause this?

 

Depending how much you moved the distributor? Moved it enough to make it run rough? Its definitly something i would be worried about depending on what it was before? Did it happen all of a sudden?

Modifications like lumpy cams will cause something like this but other than that thats a very high (lesser pressure) level of vacuum.

 

well i had to remove the distributor cuz I was installing a new Trans. After I put everything back on, I noticed that there was a leak on my wastegate so I fixed it. No new cams, didn't mess with timing belt. my idle is higher now, might be my throttle cable or something rather.

i think you just answered your own question.

 

might be vacuum leak.

 

I checked all my vac lines when I got home from work. Turns out the line to the side of my TiAL WG had a leak. I fixed it and my car is at normal idle and vac

 

yay!
