Poor throttle response. Need help!

Postby gazl2006 » Tue Mar 01, 2016 5:00 pm

Hi
I’ve just bought a 2006 350Z convertible and driven it for a week and noticed the throttle is throttling down far too slowly when in cold or warm running.

When I rev up in neutral, the throttle response is quick and responsive but the revs don’t die quickly and take around 2-3 seconds to return to idle. Other than the throttle, the car runs smooth and there is no knocking noise when idling. I know the previous owner replaced the battery and wondered whether the throttle body needed re-programming or cleaning because it may be sticking.

What are your thoughts? Any ideas what this could be and is it going to cost me loads?

Regards, Garry

Check for fault codes. Digital throttles. Great....

Check how? Do I need a friend with a diagnostics tool or is there a neat trick to display the codes?

Best to post your question in the "Z Car" section of this website.

Anyway, you can try the idle relearn yourself, it may or may not be what is causing your issue but it couldn't hurt to try.

or

Or, a Nissan dealer can do it in a matter of minutes, they can just hook up to their Consult-II machine and do it that way.

You can check for fault codes with an OBD-2 reader, you can get one at any auto parts store or even Wal-Mart, eBay, Amazon, etc.

Prices of the coder readers range from $15 to hundred of dollars.
