Apologies to all for not getting back to you. I've been living with the issue for the last couple of weeks. Threw a new fuel pressure regulator in yesterday and fixed a leaky vacuum line from the bottom of the J-boot (the one that goes to the ICV and brake booster), and that seems (from the little driving I've done) to have completely fixed my issue. No cruise control on this car, but if the problem pops back up I'll definitely throw a multimeter at the TPS.

Thanks all.
