Hey i gotta question that might help more than jus me .
What do i need to do to run my car in the cold or is that not safe. well if any one have any info on how to run in the cold let me know. and ive done a couple of adjusments i made it run more rich but it seems to not run as fast and it sound wierd but when i run it more lean it sound better but it wont let me full throttle it all it will just shut off. well all help is greatly appreciated thanx guys n advance. and this is way of the subject but any one kno of any good websites for truck rims and tires.

Theres a very fine line between optimal and lean....sometimes, I think Ive got it dialed in and it will lean bog at higher RPM.

Keep it a little rich because the air is much more dense when its cold. This translates to a lean condition if you dont adjust it (fatten the needle)
