Whenever I start my car to let her warm up before and after work (about 15 min each time) it sounds like the RPM's are fuxuating ever so slightly for the first 5 min. or so. Anybody have this problem or maybe know what it is. I'm getting the recall done this week sometime and maybe an ECU update but I'd love to know if i'm the only one with this problem.

Was it sputtering, acting like it wanted to stall/die, or making any weird noises? Or did you just notice the rpms fluctuating with no other symptoms? My guess is that it has something to do with the cam sensor, which is assuming what happened to mine today which I posted in the 'sputtering' thread.

Mine does it too.

Actually, the other day, it was doing it when I had the A/C running. I could watch the rpm move up and down slightly and hear the engine doing it as well. It stopped when I turned the A/C off though.

Mine too, no biggie. It settles out after about 45 seconds or so.

mine did it after I did the Barry Mod. Only when the sensor was off a tad a simple alignment and I was Gold.

Mine does it, kinda revs and drops for the first minute or two in the cold weather, not so much when it's warm though. When it's real cold out you can hear the engine idle up and down, and around the time you start to see the exhaust pour out of the tip, it seems to smooth out pretty fast. My old SC2 used to idle like this alot too, I think it's just the start up routine.
