2002 4Runner Hesitation after stop

Recently my 4 runner started hesitating for 5-7 seconds after i come to a stop. I press the accelerator and nothing happens, the engine doesn't rev at all and i go nowhere. After the time period of 5-7 seconds the vehicle will go as normal with good acceleration. It does not happen every time I stop, just at random times. Has anyone had this issue?

Top Culprits? Bad Pedal position sensor and/or bad TPS. You can get a denso TPS now but I think the correct PPS is still not available. There are threads showing how to pop it open and rework the brushes and traces.

Otherwise, we used to have to buy the entire Throttle Body assembly (which comes with both). Which is about $450 or so. I did this and it fixed a ton of driveability issues including a take-off hesitation. The TPS or PPS was simply worn to where the ECU had no idea where the gas pedal was.

EDIT: this is for 2001-2002 which has a somewhat UNIQUE Throttle Body

 

Ok, that was the direction I was leaning towards. I had read that the PPS was not available, so I will most likely start with the TPS before shelling out the $450 for the throttle body assembly. Thanks.

 

The PPS was available but not sure when it'll be back:

I installed the new TPS and had no response from the pedal at all. Then repositioned the sensor and had full throttle at startup without pushing the pedal. Does it have to be be at a certain position on the TPS?

 

Not sure if the TPS' are the same, but on my Mustang the TPS voltage has to be within a range of like .65-1.25V with the engine off, key on. You can measure it with a DVM, and at least on my Mustang you can 'swivel' the TPS to change that voltage. Its a myth, but most mustang guys try to get the TPS voltage as close to .99V engine off key on.

4runners may be completely different, but something to look into. The fact that you had full throttle at start up without pushing the pedal after repositioning it makes me believe they function similarly and you 'over' repositioned it.
