Hesitation/no accelerator from start

My '08 Tacoma TRD automatic with TRD intake and exhaust periodically hesitates from starting and even less frequently from a rolling 5mph and up start. There is no response from the accelerator until I let off the accelerator and press down again. I have spoken to other 2nd generation Tacoma owners who are experiencing a similar problem. Heading to dealer on Friday.

 

Sounds like something to do with the accellerator recall.... did you have it done recently?

 

In for accelerator recall, and back, and still no remedy.

 

The tacoma is a drive by wire system. The accellerator recall, from what I understand is an ECU reflash. From an electronics tech point of view, I'd start looking at a new gas pedal assembly. Sounds like the transmitter might be faulty.....


I really have no idea though.


:shrug:

 

Thanks. Hope to know something Friday. Might be something related to wire harness.

 

I'd be looking more towards the drive system that open/closes the butterfly valve in the throttle body. If it's wearing it might start to lag.

 

This could be very possible too.... they do work together as a pair. Since we've eliminated the ECU, its probably just down to these two. I would lean to the accelerator only because, in most cases, the part with the most human interaction is the part that breaks.

 

Is the throttle electronically controller or vacuum assisted?

 

Any word on what you found out??? Having similar issue!!!

 

They could not find the source of the problem however they have opened a "tech case". Not sure what that means but hopefully it means if others are having similar problems other techs and factory folks will probe deeper into the problem.

 

I'm taking mine in this week...I'm sure they won't find it. That seems pretty normal for the dealership.
