The Throttle (gas Pedal) Hesitates?

[Running Ox]

Is there anyone suffer from the very soft throttle pedal? when stepping on it takes about a 1/4 of a second before the engine responds. It becomes very annoying in traffic. Anyway to fix the problem? (2004 RX330. mileage 65000)

The RX is known for this lag and most say it is due to the transmission which may be true. However, I eliminated the problem on my car by removing the slack in the throttle cable which connects the gas pedal to the throttle body. It is a very simple thing to do. I was concerned about taking out the slack because I assumed Toyota put it there for a reason. However, I did the adjustment a couple years ago and haven't had any problems. It made a huge difference!

Did you do that by yourself or a repair shop? I am still not very clear for the "slack" you are talking about. If you could up some pics that would be awesome.

If you look at the throttle body you will see where the steel throttle cable is connected to the throttle. You can put your hand on it and manually open/close the throttle. On my car, you could open the throttle a little before it started pulling the cable. There are adjusting nuts on the cable which allow you to remove this slack. When you do that, the throttle cable begins to move as soon as you start to open the throttle. That translates to the throttle starting to open as soon as you push down on the gas pedal. Anyone can do this if they have just a little auto DIY experience.

artbuc,

You are describing RX300 fix. Running Ox has a RX330 with the common "drive by wire" hesitation problem.

You kind of have to learn to adapt to it. Did you just get the vehicle or have you had it from new?

The RX330 has no throttle cable, its electronic.

I recently perchased my RX330. I did a little research on that and knew that problem due to the E-throttle. I will keep looking into it for more information.
