It seems the 2 week rest in the garage has fixed some of these problems.. weird.
Another question i have is, From cold start the idle is perfect, sitting at about 1k rpm. When i drive a short distance (4km or so), stop the engine and start it about 15 mins later - The rpm at idle is down at around 400 - 500 and jumps up and down. It might go down to 350 or 400 and almost stall, then jump to 500 - 600 then back down again. Any ideas what might be causing this?

Just curious - what was the $700 for?
The idle issue is likely an IAC problem or a vacuum leak. Is the ecu throwing any codes?
