    Hello from New Zealand ; new to the v6mustang forum but looks like a GREAT source of info.
    I recently purchased a '2003 v6 5 speed manual , with just 75k kilometres on the clock (export model has kmh speedo / not mph ) , still left hand drive , which is proper ; pity about the speedo face though...)
    my questions first time up are ;
    the clutch pedal comes out a LONG way before it starts to engage ; far more than any other vehicle I've owned, and the clutch is good / not slipping/ bites fine / just comes a long way out before it starts to take up.
    before joining the forum today ; reading on line suggested the 'Maximum Motor Sports' firewall adjuster, cable, and aluminium quadrant would be a good help to get the clutch action a little closer to 'normal' ; just received and installed the kit and the clutch feels nicer , still comes out a ways , but it is better , BUT what has changed is now depressing the clutch pedal (loading the release bearing) gives a low grating that sounds like a worn release bearing ; you'd say that's what it is, as I would , EXCEPT ; prior to installing the Maximum kit , the clutch was quiet as a church mouse, the only change has been the install, with resulting improved clutch action, and instantly I have a growly whirring like a bad bearing when the clutch is depressed , from standing start and also on any gear change, that remains audible right up until the clutch is almost totally 'out' / foot off the pedal (needs to be say 3/4's of the way out for it to go away, and it only does this 50% of the time ; other than that it's quiet / then growly / random...) ; again , the only thing that changed was the kit install ; the car only has 75kms on it (just over 50k's in miles) so would be surprised if the bearing nuked itself that quick , or nuked itself on the kit install ; has anyone else struck anything weird like this when installing the alloy quadrant + firewall adjuster ( ? ) ; a clutch specialist down here suggested the noise was now transmitting up the cable and through the alloy quadrant / no longer a nylon quadrant to sound deaden, but not really feeling that.... any ideas / feedback will be appreciated (I've been building street rods for 37 years and never struck anything like this...)

    and for the second part ; what I think you guys in USA call 'throttle hang' ; you take your foot off the gas , clutch in to change gear , and the revs stay high / don't instantly drop once your foot is off the gas like a 'normal' throttle does ; the revs come down 'slowly' but they might still be hung up above 2 - 2 1/2K rpm by the time you're already letting the clutch back out (another new one to me , but have seen snippets about this on v6mustang site). look forward to any and all feedback on the above ; it's a nice tidy little low mileage car if I can just sort these couple of issues. Thanks in advance.

    yes the rpm's do hang a bit, but should be no more than than a second or two.

    As to the clutch.. yea don't know about that.

    I had a situation with an aftermarket clutch cable.. it seemed like after putting it in, the clutch pedal effort needed went way up. Short story, the cable was rubbing where it goes through the firewall somehow, and eventually it had started breaking the cable down right there. I switched back to an OEM cable while also adding that same aluminum quadrant and firewall adjuster, and never been smoother. So I guess make sure there is no rubbing with your cable because it will feel exactly like your throwout bearing isn't sliding well.

    I too had hanging idle and I got so fed up with it, that I made a restrictor plate for my idle air controller out of an aluminum plate, drilled 6mm inlet and outlet holes in it, and that has remedied it for me.

    The rpm hang is entirely due to the dashpot decay rate in the tune.

    I've not tried what six gun mentioned about a restrictor plate for the idle air valve so I cant comment on that. I would assume that would cause problems with cold starts, or at least throw a check engine light.

    Not my post but it's what I made.
    How to make your own IAC restrictor plate

    Three years after putting it in, never a check engine light, and wish I made the plate sooner. Personally I think it's great to use, having a manual trans with how much quicker the revs come down after letting off the gas. Yes from the factory the engine speed is designed to hang a little and come down slowly to reduce emissions to a degree, but I think I have either idle air controller problems, or throttle position sensor problems that cause mine to (without the restrictor) stay near 2k rpm in neutral until I come to a complete stop. No warning light so I haven't bothered trying to fix it electronically.

    Put your foot underneath the clutch petal and pull up. That is how you a just the clutch petal.

    That only works with the stock quadrant though.
