Yeah sorry that's my bad. I am just super confused and the vehicle is not in front of me so I am in even more trouble.
The car idles fine but physically pushing down the throttle doesn't make the rpm increase what so ever. I am stumped ???

The car is trying to tell you what's wrong... go to Autozone, Napa, etc and have them read the code(s)... it will tell you exactly what's going on.

Anything else at this point is random guessing. ;)
