7k rpms on idle , black top 4age , need help
Posted: Thu May 14, 2020 9:25 pm
The problem:
As stated my AE86 black top has an idle problem , the engine would quickly rise up to 7k+ RPMs on idle but when I put the car on gear and and accelerate the RPMs would go back to normal. In between shifts the RPMs would quickly go up again , even with the throttles fully closed the rpms would go up to 7k+ rpms
I checked the usual suspects, cleaned the ISC, new map, check all the vacuums , TPS(new) , bled the coolant and made sure there is no air pockets, timing
Any ideas what it could be?
I search the forum and didn’t find anything
Specs

Tweaked wire harness
