@veeg33 and @ Richf@H-Dev I did the first “ECU Resetting Procedures†followed by the “Accelerator Pedal Release Position Learning†which went to plan. I followed the “Throttle Valve Closed Position Learning†procedure but didn’t hear the throttle valve move during the 10 seconds wait time. I tried this a couple of times; when turning on for 2 seconds I hear what sounds like the fuel pump turning on, but when I turn off, I don’t get a click or any sound. I didn’t try the “Idle Air Volume Learning (Throttle Position Learning)†because the Throttle Valve Closed learning was a prerequisite What are your thoughts? Does the throttle body need cleaning?

Thanks guys for the feedback the reset process. I’ve also found a ProTech video on YouTube with the re-learn procedure: I’ll give it a go this weekend and update this post with the results

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, Gaz
