Check the fuel pressure, it should be 9 to 13 psi. It could be a bad injector also.
If you need injectors, get back to me. Also did you set the tps when you put the new tbi on it?

Take your air cleaner and spacer ring off. Then watch the spay pattern of the injectors. You should have a even pattern, If it dribbles out you have a bad injector.
