engine shakes

[Altiman94]

My engine shakes around 750-800 rpm at idle. The idle is still a little shaky, but much better than than it was. I redid the base idle and it helped out a little, but not much. The thing I need to know is my mechanic told me the injectors are not getting a proper signal via the electrical plugs that connect to them. Should I just get new ones from the dealer and splice them in? Also, what else can be done to fix my idle. I've cleaned the maf, tb, and redid the base idle, the timing is correct and hte aiv is not hooked up.
