Throttle response

I have an intermittent problem (which is getting worse) when driving at approximately 60kph where the car wont respond to throttle position. I can keep depressing the accelerator to around 60-70% position before the car accelerates.

I have had the problem for about 20000k

The Rodeo is fitted with a 6VE1 engine and manual transmission.

I have had the car on a scanner but nothing shows other than the maf sensor and throttle position sensor working but no error is recorded.

I have replaced the maf sensor, oxygen sensor, and idle stepper motor but none of these have had any effect on the problem.

Monitor the throttle position sensor. It could be working but at certain range it could be out of specs. Same as the MAF. We do not have any information for your vehicle so I do not have the specifications for you.

While monitoring the sensors, ensure they are moving gradually as in relation to throttle opening.
