Look dont get me wrong BUT If I was your mate i would expect you to bring it back if you had a problem. now you are coming back after a month and telling me you have been to someone and they said the timing is out 1 tooth and the air flow meter os rs.
What do you think my answer would be?????? mark it down to experience, hope your mate doesn't find out and you can stay friends.
And if you get your car returned and it is not purring like a kitten drive it straight back and at least show it to the workshop manager and get it written down that you are not happy and something has to be done to rectify the problem
