Why Did My Z, Keep Revving? Video.

TheWeatherman · 02-04-2010, 04:35 PM

Okay, here's the latest update, and hopefully the final one. First, Nissan sent down their Quality Control Engineer to look at the vehicle. He was happy because he was able to duplicate the randomly revving engine. After taking it out, taking vids, pictures and logging all information into his computer, he said he was sure of the problem. Any guesses?

From his analysis, he's went with malfuntioning clutch and neutral position sensors for the.... Synchro Rev Match. There ya go! Those both were replaced, and so far, wallah! No more problems with the revving engine.

I would like to thank the Quality Control Engineer, Nissan Corporate, Nissan Japan, and Russ Darrow Nissan for the prompt and excellent service. Everyone explained everything to me to a tee. They also completely detailed my car since I only take it out when it's completely dry, and they had it out in the salt. That was an extra touch that really made me happy.

Wrap-up... No stuck throttle, a problem that was fully logged and closely reviewed in Japan's engineering headquarters. Should this ever happen to any of you, it seems to be one or both of those sensors. It's great to have both the 2009 Infiniti FX35 and 2009 370Z back in perfect running order.

To not tarnish Nissan's name and to take down my accusation of a stuck throttle, I'm going to take down that YouTube video if I can figure out how. It's great to see this forum work in such a constructive way. By everyone's input, it made the problem interesting.

Feel free to add anything if you'd wish.

Great news! Still don't see how it could be the sensors they mentioned given that it would do it from a standstill, maybe they're trying to avoid a Toyota like recall?

Gee, I seem to recall someone suggesting that it might be a malfunctioning SRM.

Well you had an e-attitude about it... manners!

But why did it only happen to me twice, on two cold days, and never again? If a sensor is bad, it's bad. It shouldn't be weather dependent.
