the hole in the bpt hose would give your car high NOx at the next emissions testing. If it's bucking and sounds a bit rough...

muscle car noise - check for a hole in the exhaust yet?

bucking - I'd check out a few things for this one. timing, coolant temp sensor, tps settings, and also the injectors. If it's an older car like an S13, it'd probably be the injector plugs being green from corrosion or they're just worn out. Roughness at idle I take it?
