I've had this problem for a while even before head gasket blew in cold and wet weather car will not idle or respond unless you have the accelerator half way to the floor it's some kind of fuel problem fuel filter has been changed regularly spark plugs and wires are maintained I've thought of buying me a new throttle body.

This sounds like the TPS is bad which was common on these cars, I would run the codes as well.
