Hello, I have d16y7 5spd. IV had a idle surge between 1k-1,500rpms. It also drags/ putters when let off the gas.
When I start the car it sits high anywhere between 1500-2,000 rpm’s then drops a little around 1k
In the video you can’t really hear it but you can definitely feel it in the seat and see the needle bounce.

I have replaced.
Manifold gasket
Throttle body gasket
Throttle position sensor
IACV Sensor.
Distributor/plugs/wires
I have bled the coolant of air many times.
I have also adjusted the throttle screw on top of the throttle body.
No check engine light.

If anybody can help i would appreciate it. I haven’t been able to drive it…

 

Everything Iv done so far has also been done to spec. Like the tps at 0.50 Ohms

 

Could be a vaccum leak somewhere. Have you checked the vaccum lines and vaccum operated components?

 

Iv checked break booster. And the only other thing I did was put my hand over the throttle intake to see if it was pulling air from somewhere else. When I did so the engine did die off immediately
