I'm @ a light and attempt to accelerate, nothing happens. My idle was OK, but the service engine soon light comes on. As I press the gas pedal, I get absolutely no throttle response, nothing! I have to pump the pedal to get the car moving. Once in motion, everything seems to be OK. Presently, waiting on tow truck. You can see my mods, nothing crazy, anyone have an idea?

 

search the forums other people were having this prob, but i hear its nothing out of the ordinary, take it to the dealer.

 

I wouldn't mind betting that an ECU reset would probably do the trick....

but if not then the issue may be one of the other resets in 'Merlin' 's thread
such as - Accelerator Pedal Release Position Learning, or Throttle Valve Closed Position Learning, or Idle Air Volume Learning..

I've done these resets, and they're not difficult.

As to how those settings got out of wack......is anyone's guess...

The drive by wire system is otherwise beyond my experience.
Thanks Goodness for warranty.
G/L, and happy reading.

I took it to the Infiniti dealer, he said the same "...it may be the throttle body, or MAF sensor" It did feel like it could because when I got home, I couldn't mimic the problem. Bad place to discover it on a busy intersection. Fingers crossed, hope it's nothing major. Also, I did check to see if there were any loose connections

 

My car did that once a loong time ago. I scanned the computer, and it came up with Throttle Position Sensor value out of range. I just cleared the code, and it never came back. Fluke I suppose. My car seems to do that once in a while. So far in 2 years, I have had 3 unexplainable DTC codes, that weren't reproducable, and never camed back.

1.) Tranny shift solenoid
2.) Throttle Position Sensor
3.) Closed Loop Control, Bank 1

 

Well, I got my car back today. It was the TSB, so they replaced the whole throttle body. The guy said they do have intermittent problems with this. Good thing it's covered, OEM throttle body costs $732
