98 gs300 throttle ploblems. I have to floor it to maintain speed

When I start the car up it runs fine but after the car warms up I have little to no response from my gas pedal. Please help

Sounds like the pedal position sensor is going out, there is a mechanical override on the last 1/4 or so of pedal travel as a backup, which is why flooring it works for you.

Have you checked the throttle cable underneath the hood just to make sure nothing came loose? It's a possibility
