ok my car is idling funny but runs fine after 3000 rpms what changes does a vavle open or is timing advanced past that or whats up??
 
My car starts to go stupid rich at about 3250 rpms.

As far as the idling, the coil packs are known culprits for wierd things. You could also have a spark plug/wire issue. Just a couple guesses.
 
Head over to the NA tech forum and start asking lordworm some questions. That might be related to the VCTS, but not sure what RPM that kicks in.
