Ok i own a 2000 alero 3.4 with 90000 miles on it. For a while now i've been having a problem with my engine quite often. The engine stay's at 2k - 4k RPMs while sitting still at a redlight or when the car is in park. It is very difficult for me to be able to hold the brake pedal down while this is happening. While the car is in Drive the RPM's are much lower (of course), this can be anywhere from 1,200-2,300RPM's. when the car is shifted into neutrel, the RPM's go way up to around 4K.

Now this problem is not consistent at all, sometimes happens a few times thoughout the day... and sometimes not for a week or 2. This problem is really starting to show wear on other parts of the car (extra stress on brakes... Been though 2 sets of rotors, beatin on my third).

Any ideas what could be causing this? Thanks!!
