IDLE WAS ROCK SOLID - Now it isn't as solid? What could this be?
Alright, Had engine rebuilt, and everything was rock solid with the FC, took it from Phoenix, to San Diego. After putting 1000 miles on it without boost. Now the idle is a bit jumpy, not real bad, but idles a bit lower than it did before, and it jumps around +/- 20rpm are so, slight movement, and a few hickups i can hear, but it WAS rock solid.
ANy ideas on what could cause this?
Thanks,

Also remember Darren, the lower the engine idles the more inconsistent the idle will be.
How much of an idle drop are we talking here?
Mine is typically around 880 w/ around 20-40 rpm variance (8.5 lb flywheel/stock port).

So reset the PFC and let the car idle for 45 minutes???
I am saying that the idle was rock solid at 900, if you looked at the gauge, it didn't move an inch, now it's moving a bit, every so slightly, but enough to make me wonder why it's not as solid as it was.
Sure it takes 45 mins to learn the idle??
