please can you help me, I have a 2004 astra coupe convertible, at times its like there is no power when accelerating and then most the time if I turn it off and restart it the revs are there and it will drive fine again? Ive just brought a fault finder and its not showing any codes up!! Ive not long brought this car and I'm worried that this will happen when my kids are in the car as it gives no warning that its gonna do it, sometimes the engine management light comes on, but hasn't since I brought the fault finder and put it on the car!!! please can you help
