Wow, talk about back from the dead thread....
Anyway, here is what I did the other night to fix my bouncy idle.. After cleaing and ensuring that I had a working ISV, I drove around til the motor was nice and warm. Then:
Turn off the engine, unplugged the ISV and blue coolant sensor
Started motor, crazy low idle, adjusted idle screw, noticed it was loose.
Tuned off engine and reconnected ISV and blue coolant sensor.
No more bouncy idle.
Thought I was good to go.
Yesterday, car starts bouncing again. F@#(K!
In the parking lot of a grocery store, adjusted idle screw again
Then I went over to Home Depot, and got some loctite (not the red) to hold the screw in place.
After a little bit of loctite, looks like the problem is solved.
