just a question

Hey all, I was wondering if anyone else here experiences this problem, if it is a problem. I have noticed when I first start my truck, it has like a slight miss in it, if thats what you would call it. I have noticed it in alot of other vehicle not just mine. It's like a small surge or something that I can feel in my seat and in the steering wheel. I thought it would be gone when I change the plugs and wires and all of that but it i sstill there. I hav just come to the conclusion that its the vibration of the engine going through thru the wheel and pedal. Do any of you all think I'm right. Thanks for any comments.
