2000 toyota tundra 4.7 engine. when accelerating there is no response. It is flat untill you put the pedal to the floor then it takes off. I have a code 1121 (fuel metering). ---

I’m going to guess the Throttle Position Sensor. ---

I was thinking the same thing but I didn’t want to spend the money untill I was sure.Dose the code 1121 lead you to the TPS ? Thanks Bob. ---

Combined with the operating symptoms, that’s where I’d start.
