My car hesitates, jerks, and baulks when accelerating or going uphill when cold. After about 30 minutes of running, it stops jerking and runs well. My guess is that it needs a tune-up. I noted 5.0 on the engine, but I don't know if it's 5.0 or 5.8.
It's possible that your vehicle may need a tune up. If your vehicle is equipped with a distributor, the cap and rotor should be replaced as well. I would recommend help from a certified mechanic to assist you with your tune up and diagnose some of the symptoms you are describing.
