When the groove was deep enough, they unscrewed so easily with . I guess JohnL was right when he suggested that. I've got a few pics if you want to adjust your DIY.

Btw, they were done almost well enought that I'd almost consider putting them back in, instead of replacing...

Oh,very nice!

Good one mate,cheers,will add it into the DIY!

definately trying this tomoro on the jazz, since i changed the tb the bitch doesnt wanna rev up properly

I don't think the TPS on a fairly new car would be off enough to notice..

i changed my TB to a bigger one. so i had to recalibrate it.
now in my CVT honda jazz the idle speed is part of the tb u adjust the TB stop, but also when i calbriated so that .48v was foot off the car would lerch forward in D when i had my foot on the brake like the car wants to take off, because the clutch is engaged. its really wierd cause thats meant to be closed TB position. so i cant get correct response at fully open i had to calibrate it down so that off was more like .42V and fully open then subsequently became 4.42V which sucks. cant get this thing sitting properly.

Just did this last night. It was on a spoon venturi TB.
However when I achieved 4.5v at WOT and 0.48 at CT, my butterfly gets stuck when closed?
gave it a good clean with throttle body cleaner suspecting carbon build up but it still gets stuck.
Its almost like I have to kick the accelerator pedal to open the throttle.

Another thing I noticed was that if I set the throttle cable tension so that it is WOT when the pedal hits the floor, I get alot of slack at CT.
Is it okay to have the throttle rotor hit WOT before the accelerator pedal hits the floor?

I get the same issue, when adjusting to 0.48 closed the tb plate gets stuck. I simply adjust the tb stop screw abit to stop it from sticking

Yeah i just went back and adjusted the TS screw and brought it up to 0.50.
I did some research and some people say they calibrate it from 0.50 CT to 4.5 WOT.

But this has definately made a massive difference in throttle response! I hardly have to push the pedal as far as I used to while cruising.

I also just adjusted the throttle cable tension so there is little play from the pedal before it actually opens the throttle plate.

Good stuff mate!!

Maybe cleaning it up will stop the sticking,it's in the corners where it gunks up that it will make it stick.

Clean it every so often,it helps to keep it smooth.

Best to clean it when U upper engine clean it with 'super engine conditioner' from 3 Bond.

Hello to Everyone!!!!!
