Just started happening after a 60 mile highway trip. Coming up to a stop light after the first leg of he trip it stalls. And continues at every light or stop sign. I can hear a clicking coming from the passenger side footwell when I get off the throttle approaching a stop.
The truck just had a tune up with Toyota plugs, wires, PCV valve, fuel filter, and Denso O2 sensor. Truck ran awesome for 260 miles and the MPG jumped up from 14mpg to 22mpg.
I am thinking vacuumed leak but the clicking from the passenger side has me questing if it is something electrical.

Any thought or insight would be much appreciated.

 

im having the same problem but only when on a hill with a stop sign

 

Checked the codes on the Toyota and came up with code 51- Switch Signal. The check engine is not on but flickers every once and awhile. From reading on this forum the code 51 is related to the TPS. Would replacing this help?

 

You can try to adjust/test it but chances are it will need replaced. The IDL contacts wear out over time and the ECU no longer knows when it's idling. A missing IDL signal will generate a code 51 and can cause idle issues.

 

Got it to stop stalling!
When I did the tune up with Toyota parts I cleaned the throttle body and MAF. The throttle body was so dirty that it was keeping the throttle partially open. Now that I was squecky clean the butterfly valve closed more. So a idle adjustment back to stock fixed th idle issue. I still have the code 51 thought it is only on after I take a long drive. Then it dose not come back on for a while.
Where is the best place (cheapest) to get a Toyota TPS?

 

If the code 51 is intermittent, I would try to adjust the TPS first. If that doesn't work, check out toyotapartseast.com or 1sttoyotaparts.com.

 

Got a new OEM Toyota TPS and I am having a hell of a time adjusting it. I am thinking that I have the TPS on wrong or something. I have been following 4crawlers TPS adjustment page, but there is nothing on replacing the sensor it self. Is it supposed to attach to the two metal prong that are attached to the throttle valve?
