when ive just drove 70mph on e-way for bout 10miles once im off it seems like the car is idle high when sittin at a light the rpm hand seems to being kinda moving under 1 a little and it feels like it wont to shut-off but i dont .and when driving after the e-way run when im hitting the gas the rpm hand is high

Could be a bad catalytic converter.

sometimes on the e-way hiting the gas over 60 kinda feels like the engine is hesitatin

That all sounds like a plugged cat.

ok well can u tell me why the rpm hand moves when turning the steering wheel

That sounds like possibly a bad or corroded ground. I'm not sure where all the grounds are on your year.

could it be a engine mount

A engine mount? You lost me here.

I think the fluctuations in RPM when turning steering at idle are due to the power steering pump taking some power out of the engine when turning the wheels.
