I have this problem, very rarely, where when I turn on the car, the engine doesnt seem to bite correctly.

It tries to go but then just seems to tick over a few times it eventually does start but sounds likes its not going to for a few seconds.

Like i say its very rare it happens, and all i can narrow it down to it not turning the key enough, Im not expecing many replies as i know its an awful description but thought I'd just put it out there.

Astra is a 1.6 petrol energy
