Yes, check yout tps. It could also be something like bad plugs too. Mine had a problem like that, And all i did was replace the stock idle adjustment with a home depot bolt with a nut on each end. The idle screw was moving around nad making my car not want to run.

Where is the stock idle adjustment?

Have your friend move the gas pedal, look at the throttle body. The part that moves, there is a crappy screw in there with a slot cut into it for a screw driver. Take it out, Goto home depot, Get a stainless steel one out of the hardware section, and get a few nuts and lock washers. It will never move again lol. Make sure you get the bolt with the hex head too, not the screw driver kind.
