throttle/idle problems

This could be simple but is likely not so. How well does the car start?

When you say choppy throttle, do you mean that the engine misfires when you move the throttle? Does the engine rev quickly?

My initial thought is that you have a vacuum leak, but I am not seeing how that would relate to the blown EGI fuse. I am hoping that you weren't boosting when the EGI fuse went out.

You should check compression at some point if the car is hard to start. If it starts easily, compression is not likely to be the issue.

sometimes a rich smell is an indication of lean misfiring. You might also check fuel pressure, but I don't think that is the issue.
