    Hey Guys
    Have 2 vacum hoses that are just hanging. One looks like its from distributer cap and goes up to the top around carb and just stops? Is it vacum advance? And 1 that comes out of the air box post filter tees off ? I'll try and post the pictures. Don't knowif someone can tell me where they go. Also vacum gauge bounces between 15-18. So maybe mixture screws or plugs? Just had my exhaust temp gauge come on and won't go off. Can seem to load picture said file to large for sever

    After a little research the 1 from the distbuter cap is a vent.....Now for the other one.

    is it these 2? theres this one on top of the airbox that goes to the carb

    then theres this one at the bottom of the airbox that goes to the exhaust manifold, that ones likely for winter to supply warm air at startup

    Hey Maximal
    Your first picture show the hose. If you look at the inlet hose clamp just below your finger there is a 1/4 line....it clips on the side of the inlet hose and tees. 1 goes goes to a vacuum block....my other one turns and looks like it starts to come back up by the vacuum chock.....but it just stops....I can tell something is missing but have no ideal where it goes

    so it starts here

    then goes to the 3-way T. one end of the T goes to the vacuum block under the bed here

    [​IMG]

    and the end im assuming youre wondering about goes here by the throttle. where you see my watch is where the air conditioner compressor goes and im pointing towards the passenger side of the truck, where my index finger is theres a nipple under the throttle that the vacuum line attaches to. if you have AC, you probably will be having to unbolt and swing the compressor out of the way to attach it, you can see the vacuum line loop around on the right side from the T valve and go under the plastic cover towards my index finger

    also the exhaust temp gauge is actually for the cat converter, JDM vehicles have a temperature probe and if the cat gets too hot you get the dash light. usually if the light comes on theres a issue with the sensor itself or the wiring and you can just ground the wire to get the light out

    my Toyota Crown the cat was plugged and when i stopped at lights the revs went down briefly and i got the rotten egg smell, i took out the cat and welded in a pipe and just cut the sensor wires off and got no dash light even when it was plugging up and probably cooking hot in summer. my bet is the wires to your sensor maybe broke

    No worries, it's a tight fit but it feels like there's a vacuum nipple that the hose attaches to. If you end up not being able to find it I have a EN07C in the garage of my other place and I can get a good picture Saturday

    I did find where it goes. There was a vacuum switch in the front of the carburator. If v you follow the intake tube from the air box to the carb. It sits right under it. Had to get to it from the passenger side to plug it in. Seems to me that it had a much quicker warm up time from idle to full temp. I believe part #14773.. not sure what it does are the proper name. I would like to post pictures my pics are under 3 megs ....more lIke 2.2megs. That what's supposed to be the max for posting. Don't know

    I did a compression check and got 180 psi,180psi ,185 psi,185 psi. So the motor seems to be strong with those numbers. The only thing left to fix is the exhaust heat sensor

    interesting that it made it warm up faster, summer mine has no issue with the water needle getting halfway after 5 minutes of idling but winter when its below -20c it takes 20 minutes of driving to get halfway and if i stop at a red light for more than 2 minutes the needle starts to go down even lol

    Sense you have a parts book. Can you find out the name of the switch. I believe the number is 14733

    Page 96 of the manual under fuel & exhaust. Calls it a Thermo valve
