I have a 2001 Chevy blazer 113,950 miles and it's starts up good and accelerates good but slightly jerky, when I come to a stop it's gets really rough almost like it's going to die I'm not sure what the problem is thinking it's the ignition coil since its the original one since 2001. Also I have all new spark plugs wires cap and rotor and I have a new fuel injector and fixed Evap and vacuum leak so I'm thinking it's ignition coil since its the only thing I haven't touched. Also very strong smell of gas like running rich. And pops a bit when I rev it

 

I'm not an expert, but a good starting point for clues is if you have and OBD codes.

Also, what brand of rotor and cap are you using? Conventional wisdom here is that only ACDelco parts will do for these.
