My car drives a short distance, like 15km and then the revs go down and it's like it is lossing power and eventually dies, and does not want to start until an hour or more later then it starts and drives normally for another 15km until it stucks again. I took it to two mechanic shops, the first shop said it was the injectors and they cleaned the injectors but the car did the same, but then they said it was the airflow regulator but couldn't find a replacement, then the second place said it was the petrol pump and I let them put in a new petrol pump but the car did the same thing. I think that it might be the airflow regulator but everywhere I look I can't find a replacement.
