Of course I did the air filter, oil change, and spark plugs first. Even did the VCGs and upper timing chain cover gaskets. Throw the CCV in for good measure. Still think the fuel system cleaner did the most towards smoothing the cold start. I figure the fuel injectors had crappy spray patterns which caused the cold start symptoms.
So is it fixed now? Mine is acting all weird it started smoking the other day smoking blue smoke and I'm thinking it might be the oil separator but not sure
