if the engine runs, but it is bouncing, i would suspect motor mount(s). why a "tuneup" would break motor mounts is beyond me. if it aint running, good luck

I bet your front engine mount is broken. This will cause a CLUNK sound when starting from a stop unless you feather the throttle and **** of the folks behind you. It will also clunk when shifting into second if you are giving it any gas at all. The most likely reason it happened after a tune up is you wanted to check out the tune up by stomping on it and letting wind it's way through the gears. This puts a strain on the fron mount and the old rubber breaks. Well that's what happened to me.
