Dear all,
Hope here is right place.
1991 integra b18A2 AUTOMATIC

S4 Bulb flashing all the time .
I was intending to oserve the OBD flashes by ciruit the OBD cable but now I decidet not to do this.

So what is the potential possibilities about this S4 light flashes al the time ?
S4 button is not making anything.
Also during running on the road OK but when I am coming down slow and push the gas pedal again It can not making the gear smaller .Yes it ca do somethimes but It makes Different sounds and vibrations IKE :
Imagine that yo are driving your MaNUAL car like 20 km but your gear is on 5th :) Crag grukkkk
Soon this time I push the gas fully then it will be k OR I am using 2 only.
Also ENGINE light is running all th time .
I have not checked yet the engine light fault code..
King regards
Okan

Throtle position sensor makes difference. if it will be unpluged or not? (During idle?)
