Strange Crunch

[joshm35]

Hey guys,

My names Josh and got my 1st 01 m35 yesterday. All is going good but i have this little niggle. It may be nothing but i have had it on full boost then when i let my foot off the accelerator, there is this like crunch sound/ feel under my foot. It doesn't do it all the time just every now and then. Any ideas guys. Just not hoping its much.

could be something as simple as the spring in the throttle making a weird sound.

how loud is it?

Get under the dash and check out the condition of the throttle cable, make sure its not slightly frayed and making that sound. Also WD40 the linkages too and see if that shuts them up

That'd be a good start ... eliminate them as being possible problems if anything.

good advice, except M35s dont have a throttle cable

they have a potentiometer attached to the pedal. apparently early V35s had problems where this would wear out.

but like Ruby said, stick your head under there and have a listen to where its coming from

only makes the sound when car is moving, i was thinking gear box but it would do it alot more than what it does if thats was the case. Thanks for the info guys ill let you know how i go.

Word of the day!!!!

Well it hasn't done it again so fingers crossed it was nothing.

keep an eye on it. if youre backing off the throttle from hard acceleration, it might be a worn or dry bush in the front suspension that is making it happen.

Alex, you like that huh? thats its actual name. its a variable resistor

[joshm35]

Thanks for that zei20l, i was going to get that pedders suspension safety check. Cheap and informational.

Probably worthwhile for piece of mind even if its not related to this problem. a 2001 will have started 'getting old' the last few years. i know mine needs some bushes done too!
