thats when you block off the hole inside the throttle body, as mentioned above. if the valve is fully shut [once warm], when you cover this hole up with your finger it shouldn't effect the revs at all. im pretty sure thats the right way around... :lol:
ive actually got rid of my idle up valve all together, just got an alloy plate screwed in to block all the holes up. alot less water lines goin all over the place that way too! only problem is it idles a little bit low when dead cold sometimes, but nothing major.

and as for the surging at a steady speed - you meaning you can't "ease on" the gas, or hold it to keep your speed steady? that would probably be a dodgy TPS. i spent ages trying to set mine exactly right, and rechecked all the specs again and again and they were sweet but it kept surging. swapped it with another one, set it up once and it has been going mint ever since.
repowered - if you're coming to taupo on nov 18th come see me; ill show you how mines set up. mind give you some ideas for yours.


hey yea i'll be in taupo, yea id been keen to check yours out . It was surging like couldnt ease on the gas and also was hard to keep steady speed.

BUT.......

all seems to be fixed now. was just the way i had blocked off a vacum hose. needed to block them off indivudualy instead of looping them around. drives like a diffrent car now :D need to find a better way of blocking them off rather than a bolt, might get em' welded like jebus's

when i put my finger over that hole the engine probably would have stalled if i hadnt taken it off, not 100% if it was fully warm though

yeah thats the exact problems mine was having; its to do with the TPS or could be the timing/dizzy wiring too.
i actually found a thing on another manifold which slides over the vacuum inlet and blocks it off, havent seen them around before though.
i'll be in taupo so i'll come check your car out :lol:

AFTER



All I did was see that one thats just looped around (hose in a U shape), i just had to block them off inidivudually which fixed it. just cut that hose in half to shove bolts in there tight. will probably sort somthing better out.

oh it was the vacuum hoses on the idle up thing...i thought it was the vacuum hoses on your manifold.
ive got a diagram with where every one of those hoses should go an which can be blocked off together and which need to be separate etc if you want ot to make sure youve got it right.

you dont actually need to connecct 5 and 6 up right? you could just leave them open?
im having idle issues with my 4age now.. loping really bad.. thought it might be HG cause my water pump is real bad and puddle on ground got rainbow effect. but i did compression test and i get 170psi on all 4 cylinders.

if you're not going to connect them up you may as well remove the entire idle up valve and just block the hole off on the bottom of the throttle body.

without connecting the appropriate water lines to 5 and 6 the wax won't melt and the valve will stay wide open constantly. this could (possibly) provide the engine with too much air and end up with the idle fluctuating...
