Anyone know what would cause this car to lose power on hot days, it's fine if you leave it to cool down for half an hour and runs perfectly in the mornings, however if you stop the car and then restart it straight away it is slow to pick up speed even if you floor the throttle. The only way to get it to run well again is to leave it for half an hour. Any suggestion please.
