hi my 2004 infinity 35 coupe is not accelerating right the car will start but will drop in rpms and drive at 2mph i changed the gas petal and sensor and changed the brake pads but the same problem occurs does anyone have a idea whats going on?? or what my next move should be??

 

you're having problems cause the infinity is a well known chinese knock off.. You should have bought an infiniti if you wanted the one made in Japan.

 

well known that coupes dont accelerate well. should get the sedan

 

It sounds like the engine is going in limp mode. If the MIL light is on, get a code reader and check the code.
