I have a 94 accord ex-r with 304000km.
While driving if I depress the clutch, the engine will idle at
2000rpms, and when I come to a complete stop, the car almost stalls
before stabilizing at 700, though sometimes the engine will just die.
I have replaced the IAC valve, cleaned the EGR ports and EGR valve.
I have an engine light that comes on within 2s with code 1 (O2
sensor). I bought a new Bosch sensor and the light still comes on. I
checked the voltage from the sensor and it does fluctuate.
Under gentle acceleration the engnie will stumble at 1500 and more
noticeably at 2500rpms. If I accelerate heavily there is no stumble.
The timing belt and water pump were recently replaced as well.
This problem is killing me, so if anyone has any Ideas, please help!!
