Have you checked your fuel pressure and volume? You may not be getting the ful sufficiently to the injectors. Also, change your fuel filter if you haven't already. Is the check engine light on?
The engine stuttering sounds more likely to be an air leak on your brake servo system, weakening the mixture, and this will give you a lumpy tick over.
As for the stop lights, No 1 check its not the fuse.
You need to confirm you are getting a live feed to the brake switch with a 12v test light.
If OK, bridge this connection and recheck your feeds at the stop light bulbs.
