I hardly ever come across this in fl but as of late when I come out int he moring and its real cold out my car starts up and sputters like a mother and if I rev and let it fall it will stall out once it warms up it runs fine no biggie just wondering if anyone else has encountered this

 

mine does this also, but it really needs to be tuned...

 

I thought it may have been my valves so I adjusted them and to no avail...maybe I need new plugs.

 

IF you needed new plugs it would do it constant not only when cold.

 

thats what I thought...Im stumped

 

what kind and weight of oil are you using?

 

mobil1 10w30

 

I can not think of anything that would cause this. I am stumped.

 

same here... I don't really care that much its just kinda wierd thats all

 

Do you have your coolant lines plumbed like the factory says or did you bypass the FITV or throttle body? What year is your motor? Have you checked to make sure your coolant system is properly bled?
