last couple days my car seems to be acting different...it needs a new exhaust pretty bad....i was wondering if this could cause some hesitation and the feeling like it's going to kill....??? think i may just replace the cat when i put on a new catback....cuz i get that rotten egg smell a lot....listening to my tail pipe, it's raspy, and kind of oh...what's the word...jumpy/jittery/kinda like it's convulsing, but the engine sounds fine....so i really hope it's not an engine problem, cuz i don't want to afford that right now what do you guys think???

 

and i just replaced my plugs and wires about a month ago...

 

yes there is a chance its the cat also run a good bottle of fuel injector cleaner in with 93 octane

 

Sounds very similar to the problem I'm going through. Hopefully, that's not the case as it can get expensive.
