For the hard starting, check your pressure regulator. It might need changing, hope that work out well for you.

Yup, that's the only way you would know. Try consulting with a mechanic first too if you want to be sure. Cause where I'm from, I can ask them to put the part and see if it solves the problem, if not then I don't have to buy it. Ofcourse, not all parts are allowed.

it could be the throttle cable is stuck or too short that's why it won't open all the way, or throttle body is bad.
