does anyone experienced a problem with gas pedal not giving gas? I'm depressing the pedal all the way down just to give enough gas to move my 2001 SR5 4wd. besides VSC/TRAC, ABS, Check engine lights are all on, I had it scanned and the code read C1203. The mechanic inspected everything but didn't find any apparent fault. We are suspecting on the throttle or ECU. Any ideas why it's happening.
