Hi everyone! Im new here, just bought myself an E34 530 V8.. I was hoping someone might be able to offer some advice..

Basically, once the engine is warmed up, if I plant my foot to the floor then the car does not accelerate smoothly, it hesitates up the rev range.. What's strange is that after accelerating roughly like this a couple of times, the hesitation then vanishes and it accelerates smoothly. Does anyone have any ideas what might be up? Any help much appreciated..
