My 2004, 5.3L, 4x4 spudders when ideling or stoped at a light.Also running the idle up you can feel it till 1700rpm, driving down the roadit goes away. Had at the dealer three times, said couldn't find any codes but they can feel the spudder. Checked everything, furl pressure, compresion, injectors. Said they checked out fine and that the only way to find out what it is is to waite for it to quit running. Another respected mecanic said to have it put on an engen anlizer, that will tell you what the diagnostic wont. Another thing is after you start it and take off when the engen is cold you can feel a clunk in the gas pedel when it goes from first to second gear. Any Info Thanks Craig.
