Rough IDLE problem

[twocanewayne]

Hey , got a quistion. My 95 TSI AWD has started to idel rough when I have it in drive or reverse. It was before friday smooth all the time. Whats the problem u think.. Thanks in advance for any input And I did search first, maybe a boost leak? Maybe a vacuum leak?

Oh yhea in drive and not moving,just when I have the brake on.

I'd check for vacuum leaks by running the motor at idle and spraying the vacuum lines with carb and choke cleaner and seeing if idle changes. If it does, start replacing the offending lines.

What kind of vacuum do you pull at idle?

Keep us posted,

its 50 when ideling and about 30 in gear when in gear w/brakes on.

Now its running fine! thanks it was a loose line.

But isnt that kinda Hi though??Thats 48 lds at 1k on the tach. I thought 20 lbs was the norm. do you think its a boost leak? I can only boost 5 or 6 psi w/a t25 hooked up straight to the ecu.

I searched and I am hoping it is reading something called hkpa. It must be or something isnt right...any clues??

 

[twocanewayne]

My car and every turbo car I've seen sits at 20 vacuum when idling
