Gen 5 V6 throttle delay

I did a search first and have found reference to other cases of this. I just got this '06 with 35K and it seems to delay when you step on the throttle, just a second or so. Once off of idle and up to speed it's fine, just a little weird to get used to.

I also saw some reference to a TSB of some sort but it looked to be for '07+, can anyone comment on this?

its normal, that's the drive by wire throttle. you'll just have to get used to it.

Isn't my '06 Tacoma V6 the same way? It has no delay... It's just weird...

It's called shifting gears. No it's not normal... if you are in the right gear, the throttle response should be tight. I don't know about gen 5, but that's the way in Gen 6+.

No problems with mine, unless my car is in 6th and it needs to be in third because I just smashed the gas.

false...what the above people said is true.. i am not sure what the system in the tacoma is, but with the drive by wire in the gen5 this is somewhat common.

also worth mentioning, since the car is used: car needs to learn your driving habits, so it's probably not used to how you drive. easiest way to speed up this process is reset the ecu. disconnect the battery, and you'll have a blank slate to start with.

x2

i used to reset the ecu(disconnect neg cable from battery for 10 mins or so) and then drive it like hell, but that ended up creating a very hesitant feel in stop and go traffic. now i just drive very slowly and keep the rpm's down during the learning curve and i have no problem with jerkiness and hesitation.

since we're on the topic, and yes... i felt lazy to search; might as well have the information here since it's been mentioned

how long after the battery is reconnected does the ECU learn the driver's habits?

it constantly takes your right foot input and takes it into consideration. if you drive it like hell for long enough, it will change how it shifts.

Suggest with neg. battery off. Pump brakes a few times or head lights on. (bleeding residual power) or leave sit 30 mins without battery connected. Put ground back Then start car. with no acc. on.run it for a few mins. Do not touch the gas pedal. Stop it pull neg. again replace ground. (you have just done a clear and reboot). Then drive it hard for a few hundred kilometers. Most learning is done in that time frame. Yes it is always learning but those first few hundred are the most important.

I remember when Ford first came out with an ECU. Christ you would start that car after a reset and it would race up and down (rpm) sputter, cough and almost kick you out of the car until it relearned.

EDIT: Oh and the fun part if you do not like your reset after about 1000kms you get to start all over again. You just have to love computers.

Who would ever "thunk it" driving around in your computers.

Oh and on a side note. For the new 6speed owners. You get another set of issues with that tranny. It gets to learn your driving habits as well. So you get to trade off throttle response with tranny smoothness.

Have a great day.

so the fun part drive it easy for a smooth tranny. Drive it hard for throttle response and a rougher shift. Its a trade off. I would go for something inbetween.

I contacted the dealer where I bought my Tacoma, he said that a TSB may fix it. I'm taking it in next week to get the ECM flashed. I'm guess that flashing the ECW will also "un-learn" what the previous owner taught it.

I borrowed a OBD2 scan gauge from a friend for something completely different, I wonder if that can clear the learnin' with that?

Good on the TSB, no luck on the OBD2 will not reset that. Need to pull the power.

The flash will involve a reset BTW
