Throttling hard comes to rough idle an gas pedal works for a minute then rough. It acts like it wants to shut off, push pedal to the floor no truck movement. So turn ignition off restart and go as far as it will let me until it does it again.

Hello, I am Danny.

Quick question first. Is the Check Engine Light on? If so, that will tell where to begin looking for the problem. If you don't have access to a scanner/code reader your local auto parts store(Pep Boys, Autozone, O'Reilly's) will do this for free. I have attached a tutorial showing what is involved. Hope this helps and feel free to ask any questions. Thanks for using 2Carpros.
