Horrible startup's recently.
I've gone out to jump in the car to go somewhere, doesn't matter what time of the day or night, after sitting for periods of twelve hours or better, she'll start up horribly.
To describe it, it's like starting up a small two-stroke motor that is bone-cold or flooded. It'll barely rev and kick a few times than snap out of it into normal RPM. My 3.5 is doing just that, you start it up than it goes quiet and a few second later builds up RPM. The whirling I experienced before is not present, but it "taps" like a bastard for a few seconds. Swapped my rocker arms twice now. Starting to think it may be the SRV valve?
As far as the chugging start up, either a bad coolant mix or maybe a vacuum leak I assume?
Thoughts would be nice guys thanks.
