Check engine light is on and the code is P0455 and the rpm have been dropping to where the car shuts off if there is no acceleration being pushed. Even then sometimes the rpm just drop and the car shuts off. Battery is fine just changed that as well as everything for the catalytic converter and ignition coils.

This can be the EVAP solenoid stuck open or something else, maybe a bad or loose gas cap. See picture for location. If that is not the problem then have it smoke tested by a mechanic. Also, check for a vacuum line off.

Also just got it scanned. All the codes that came up were p0421 (which I had already fixed but It just came up again)(warm up catalyst efficiency below theahold bank 1) P0102 (mass or volume air flow circuit low input) and P0455 came up twice.

A mechanic should check all these out as it may be a wiring issue or O2 sensor/converter problem. You might have a converter starting to fail for the 421 code. But have it checked for shorts, vacuum lines off, then smoke tested to see where the EVAP leak is as a lot of times one code will cause another to pop up.
