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.
