I changed and tightened the belts on my G and it seems to have solved the problem. My shifts are smoother as well. I don't know if the belt would cause this though????

crap.. i might have to do the same...
well as long as it fixed it.. hahah

did you fix it yourself? How much did you pay?

We have two belts, both about $20 each. Didn't take me long at all to finish the job. Refer to the FSM.

Everyone Replace And Tighten Both Belts, Clean The Throttle Body, And Replace The Air Filter!!!!!!!!
