I have a 2.9 corrado with coil pack. I have a problem that sometimes when setting off from junctions or driving along and the car is under load, when i put my foot down, the engine dies, completely and suddenly, it has no power and the engine stops, car still rolls tho under gravity, and then suddenly, the engine will cut back in and run like normal, altho it gives me whiplash! Once i did pull over and the engine just reved up and down to near stalling point, then caught itself and came back then nearly cut out again, i pressed the throttle but that didnt help or change it doing what it was do
