Jake,
Possibly the jarring over the cobblestone caused an elderly catalitic 
converter to bust up its ceramic core which caused a partial clog leading to 
low power. Can you get up to speed (slowly?) and cruise at low RPM’s OK? 
Something like this happened to me once and I was able to verify a clog and 
get home by taking off the O2 sniffer cap on the J pipe right before the Cat.
