two weeks for two injectors?? I put 8 injectors in one day all the time! How about a trip to MI?

Sounds like they may have missed something on there repairs..

update,

called dealer, they found yet another bad injector, after 3 days of testing, said injector returning to much fuel to tank, that was causing vibration on acceleration. gm will not replace all, only bad ones. 3 down , 5 to go.
