revving up

[warnerTA]

ok so i started my car and i noticed that it is revving high, i start it this morning and it revs up to about 1500 like normal then it drops down to about 1100 and stays there. its a A4. and i notice that if i drive it will pull itself up to 25-30 MPH by itself i wont even have to touch the gas?? its will accelerate by itself? any ideas?

thanks

Check all your vacuum lines. Make sure nothing is holding your throttle body from closing all the way.
I like checking the free stuff first.

i have checked my vaccum lines, they all look good. i blocked EGR and blocked that. i hope its not that. and the TB does close all the way. sometimes when it does this i can rev it up to about 4 grand and it will go to a normal idle. i dont understand lol
