Car is a 2013 GT and has a couple of times started rough from cold. Each time the car had not been started for a couple of days, but started first time with no warning lights, and went quickly to cold tickover of 1500rpm or thereabouts.
However, its started noisily, like tappets/similar didn't have enough oil, was a bit rough as though the spark wasn't strong enough, and this lasted for about 2-3 seconds. Once started its fine, and has no problems actually starting. Its just rough when its been sat for a bit.
Oil level is fine, no other problems, other than suspected boost leak which I'll post about later.
I've had a few 2.5s (99, 03 and 07) in the past and a 2.0T (05) but not a late 2.5T - is this common or symptomatic of something else??
Ta for any input
