I will be driving along and suddenly the warning lights starts beeping and I have to stop, turn of the car and then it is fine again some times for days, months other times seconds. Today as I was trying to speed up into traffic it felt like there was suddenly an air gab in the fuel and then it kicked in again. This happened twice out of the 5 times the car started beeping. It is really hot outside and I have been driving over a lot of bumpy roads but that is all I can think of. So what do you think it is?
