give the IAC valve a good cleaning as well as the TB itself. I am not sure, but I think a reading of .86 on the TPS is too low, check your chiltons. Also, if your 88 is speed density, that may be your problem. I have numerous friends with speed density cars that idled so poorly they had to sell them, and refused to be fixed. You may want to consider switching to mass air, better for the Nitrous anyway.
