Most of the weeks happens 2 or 3 times, but has happened more than once in the same day. If the car is off for a long time usually doesn't happen. This weekend I left the cap loosely tighten and the car has been starting very well since. If it continues this way I'll buy a new cap.
Thanks
Got the new wheels on. They are Stuttgart ST5's will put some overfenders on it soon as the wheels stick out a little bit and will re paint matt black. Sorry not the best picture will get more tomoz.
