I'll bet the brakelights not working are directly related to the new
trailer wiring... as for the throttle response, it could be a lot of
things, but I'd check the throttle position switch first. Most years have
two, the one that tells the ECU "I'm idling" is the one to test first.

Of course, it could be weak grounds, dirty contacts somewhere or a bad
vacuum line... though I assume that (as a long-term listee) you've already
taken care of all that.

Then there are the infamous tempII sensor / oxygen sensor issues, it seems
that these two components can conspire to produce *any* bad-running symptom
at all...
