Idle issues when cold
It seems my car is starting to exhibit a issue and not sure what it could be. Was really bad today. I left work, so car was cold, started it up, and the idle went up to like 1200rpms or so.. Then the car started to shake and sound bad. I looked at the rpms and noticed the rpms were jumping between 1200 and 500rpms all erratic around that area. Then I revved it up a little, and it stopped. Anyone have a idea what is going on? I noticed this lately but not as bad as today. We had a pretty good temperature change today, and it's been raining the last few days.

I have the same issue on my 07' HR with HFC, engine hesitations when cold start, did you solve this trouble, and advise me ? Thanks a lot !
I read that it should be a lean mixture issue ?

The issue solved by selling the car! :P
Actually I think it had to do with the mods. One of them at least. Maybe the HFCs or the UPREV tune. I had a cam position sensor fail on it later after this post before getting rid of the car. Replaced it, and it was good after that. Not sure if that may have been the issue or not.

It didn't completely fail. It was acting bad when on the track when I was pushing the car and I was loosing power and WOT. Wish it did, would have made things easier to figure out!
hellsoldier, Do you still have your cats? I think it seriously has something to do with the cats and tune combined. Not really sure. Try running in stock tune for a while since you can do that with UPREV to see how the car responds.
