Iddling Problem

[audiction01]

When I turn the car on Im getting really rough iddles. The rpms on the car go up to like 1500rpm then dropp to about 750rpm even after runing the car for a bit. I popped the hood open and noticed that my engine shakes quite a bit a little too much than normal. I did my research on google and also here on the forumns and read that it could be an issue with the DV or PCV maybe even a throttle body allignment but my question is; do these problems make the engine twist the way mine's going? please help out guys any input is greatly appreciated...

Sounds like it could be a vacuum leak... do you have a boost gauge by chance?

[audiction01]

no, no boost gauge im 70% sure its the pcv i will check it tomorrow and see how it looks... thanks audi skate snow

Just a thought-

Take off the engine cover and look for any signs of oil drip/residue (under the cover and around valve cover lip / PCV area). A bad PCV can cause oil blow-back or even cause the valve cover to leak.

had an intake manifold gasket leak and a bad pcv valve...
