In all of my previous cars you would crank them and it would sit at say 1800, solid. then down to 1500, then 1000, then to its final idle point, but at each point it would stay a solid rev.

With my tC when I first start it in the mornings, it kind of bounces from 1k to 1800, until it warms up, never really staying at one place. Is this typical, does everyone else see this as well? I basically start up, it starts at 2k, bounces down to about 1200 then a quick bounce close to 2k, then it is less of a bounce to any one rpm. finally resting at about 750 rpms once it makes to to the first 1/4 mark on the temp gauge. Am I going crazy or does your tC do this as well.

Confused.

I recently added the K&N Cold air intake system without many ill nor improving effects to this idle situation, however, should I reset the ecu now, and what is the procedure, warm engine, idle for 15 mins with no loads? Obviously it did this stock and with the aftermarket system as well, but this is my first obd-II car.

is the initialize procedure that which requires one to reset all the windows and such or is their something else they are hinting towards?

Thanks for the reply.

Also since I'm still in my break in period should I wait to reset it, obviously its only had about 500 miles worth of driving so far. I put the intake on but continue to drive it like a grandma
just a more pronounced whistle, a few times I heard that classic intake drone at about 3k, then it was on to the next gear. Again thanks for the help look forward to your response

Thanks for the replies guys, I'm going out of town for 4 days, when I get back I will reset it and report back. Is it typical to do it cold or warm? I was thinking it would be best to learn how it is driven, obviously it starts cold first
Am I correct or should the car be warm when doing this whole reset procedure?

Thanks, Josh
