Thanks for all the help. I took the advice and tried the most inexpensive, the balancing. It worked wonders, no more shakes. However now that I can drive over 50 mph, my cruise control doesn't work. Mechanic told me I need a new ECU but I think it MUST have something to do with the size of the tires. Since it's not reading the speed correctly maybe it's confused. I don't know..
you dont need an ecu, hes just blowing smoke up your hind end. you just need the one already in there to be re-programmed, its a simple and inexpensive fix that i think advance can do for free, dont hold me to that, i know the manager at the advance down the street. but i dont think the 20's would cause that, b/c i have 31's and they register 2-3 mph above the speed that im goin. just a suggestion from a washed out 18 yr old.
Thread closed - the man got his help and was even grateful, however nothing good can come out of its resurrection. He likes big wheels, you and I don't - whatever to each their own; lets not make another JU
