Tps needs setting, and you have an air leak
Have you wound the idle screw down? Have you done a proper cold start setup, or did you not worry about it and leave the cold start valve under the throttle body still attatched?
Car - AE86
motor - Small port 4A-GE
use - supposed to be my daily
problem - has funny idle, no throttle responce & no tacho reading.
occurs/started when - starting the car.
personal situation - need to fix these before i can drive/register the car
No tacho: ok so i need to know where the tacho wires are in the engine bay so i can join them into the engine loom.
Funny idle: it revs up and then down over and over again. see this video.
No throttle response: it just dose nothing ... i open the butterfly and it just gets louder.

1986 AE86 JDM GT-Apex Levin Notchback ready to roll......
do a diagnostic test on ecu. some sort of sensor error.
mine did that when i first fired mine up, turned out to to be TPS.
unplug the TPS and see if it helps, it will run pretty good without it (if it is the problem)
damnit i was beaten by nicjoe!

i can hear that it has a massive vacum leak from somewhere. that would cause teh hunting at idle
it is revving way to high for idle and by what is happening when you crack the throttle, id say your timing is way to advanced.
the tacho wire is a black wire that should be on the drivers side, near the strut tower. SHOULD be.......
check your tps, sound similar to mine when the tps came lose and the wings off the throttle weren't moving the sensor. as for the tacho i assume by your comment that it is not related to the engine trouble, as in didn't previously work?
damn i got to think and type at the same time, you guys are too quick!
ive checked for vac leaks.. the tps sounds more like the problem ... as i moved it a little bit and it and it slowed down the idle a lil... but if thats the problem then that could also explain the no throttle response ... ill try this tomorrow morning.

the tacho hasn't worked when ive owned the car ... but in saying that this is the 2nd time Ive started since Ive owned it.
so the no tacho part is more a question of wheres the wire ... if someone could provide a pic that would be nice... otherwise im going to go hunting for the wire mentioned above by slide86
i will also check my timing.
the cold start system under the throttle body is still there but i have blocked all the pipes off as i couldnt work out where they go ... if someone can explain that it would be nice to ...
also thanks very much for the quick response to this... i would have to say this is the best response ive had to a tech question so far.

take it off completely and make sure it goes in properly and tighten the fkn screws up! i have failed with this previously...
the two pipes that come from under the throttle body are for aircon?
