When it's 10 degrees or below outside and I go to start my car, it never starts on the first try. It sputters for a second and i have to start it again. Does anyone else have this problem? It only happens when its extremely cold outside. Thanks in advance.

 

sounds like the tune....
ive started my car in -40 temps after sitting out for 14 hours in the open at work.
not once since ive owned the car has it not started...

 

what in the tune could make it do that?

 

Its the tune. Probably not enough enrichment at such a cold temperature.

 

you have 60lb injectors? or 42s?

 

42#ers. Will it hurt anything?

 

It's less about fuel and more about spark.

Temperature can effect your starter and how well it gets a initial spark for a startup combustion.

Cold start in your computer will pretty much always be overly rich, that's how it's supposed to be. As your engine warms up, then it will leave cold start fuel enrichment.

If you have a wideband, you'd see exactly what I'm talking about.

 

well i cant see how he would **** up your tune bad enough to cause that.
you already have the S2 tune with 42lbers so he shouldnt have barely changed anything.

dunno man, check your air filter, and spark plugs.

 

It's weird because it only happens in extremely cold temps. It starts on the second time every time though. It's only in the morning after a cold night.

 

Read what I typed before.
