I tried to a search and found a few threads, but no one was ever clear on the fix. I had my car tuned by the RX7store back in 2007. The car went into storage until fairly recently. I notice that when the car is started cold, it starts and idles perfect. However, if I go to move, the car hesitates when I first step on the gas lightly and release the clutch. It also bucks when rolling slowly through my parking garage. Once the car gets up to temp, those two issues go away completely. I have a Commander, but no Datalogit yet. It idles at 14.7 a/f pretty steady when cold. Any ideas? Thanks and sorry if this has been discussed a lot before and I just missed it.

 

After more reading I'm thinking I just need to add some fuel in the water temp correction settings between 10 and 30 Celsius. I think the car runs fine by the time it reaches 50 degrees Celsius. Anyone that can confirm this please let me know. Once the car is cold again, I'll probably try it out and see what happens...

 

Have confidence in you findings, and then search the forum on this subject..

 

Getting all these little driveability issues taken care of can be time consuming. It's not something that a shop can easily get dialed in in one afternoon. It takes a lot of testing and you may have to continue to fiddle with it some.

 

Oh yeah. I know that. It's always an on-going process. I adjusted the water temp correction a bit at 30 and 50 degrees Celcius and it seems to be doing a lot better. However, I need to just play around with it and dial it in. It was kind of hard because the car heats up pretty quickly. ha ha Thanks for the encouragement.

 

How 'cold' was cold?

 

Right around 30-34 degrees Celcius and ending somewhere between 50 and 80 degrees Celcius according to the PFC. It doesn't get too cold in Hawaii.
