williams f7r engine , no catalytic converter or power steering .
2" stainless steel exhaust system .
engine runs great and pulls like a train .
but sometimes it will idle like this in the video from cold,
once the water temperature is over the first line on the gauge
everything is fine.
does it for the first 5 minutes from cold .
when driving i can feel the power is going down slowly but as
soon as i dip the clutch pedal revs go up to normal . so it has got
something to do with the engine being under load !! ??
