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

how do i check it? do i just replace it?

rfoo

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.

ok well i replaced the fpr and the cam sensor and no diffrence the po is saying that the ecm is bad but i,m not sure one more thin i wanna know when the key is on and the car is not running i can pull the intake tube off the throtle body and when u press the gas pedle all the way down its only opening a lil bit its not opening all the way up is that normal when the car isnt running?

rfoo

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.

yeah i was wondering bout the tb cuz it dont have a cable running to it i think its called drive by wire or something like that
