No it's not dandruff !!!

I swapped out the altitude adjustment compensator last night.

Heres the skinny on what's going on.

The car's RPM will stay at say 4500 if I shift out @ 4500. Only with the clutch depressed for more than 10 seconds will the RPM's drop.

Here's another scenario of what is happening.

If I am sitting at a light in neutral waiting, sometimes the RPM's will slowly climb up to 3000 RPM by itself.

Any other thoughts guys?

Ignition related ? Maybe ? Due to the fact that it is not a constant problem. It is only sporadic. But when it does run seemingly ok it still lackes power !!!
