after about 10 sec it runs fine. as long as i apply the gas slow it will not buck. if i am going up a little incline or a hill it boggs down and bucks a little. in about 15 sec it starts to accelerate good. it will still buck now and then when cruising speed.i do not have any codes stored.

    Good tune up should do the trick! Plugs, plug wires and possible coil pack as it can cause a misfire on one cylinder only! Sounds like you have a misfire causing the "buck" you mentioned.

    I only changed the plugs so far. Runs good now but i am going to replace the wires. I did but some dry gas in the gas, and i am using a higher octane gas. Thank you agian.

    Cool! Good idea to change the wires as well. Use a good brand, say Motorcraft. Also some injector cleaner with Chevron Techron will help!
