Is there any way to lean the car out on cold startups? I'm having off and on cold idle issues (idles will surge on startup and the car will eventually die) and the AFR is rather rich (around 12 or 13...a few times it's gone so low it doesn't even register). Afterstart is at 0 and TPS enrich is at .3. Should I go lower than that or will that now affect idle?

Warm start seems to be fine and even though idles surge after it's started it's not as bad once the car is running/moving for about 30 second. Seems like the colder the weather the worse it is.
