OK so i just go done with my b20V a couple week ago every thing is find but my IDLE is Weird when you start it it idle at 800-900 the it drop it 300 to 500 constinly back and fourth, where the motor kind of shake and sputter so to make it quick my car is 96 obd2a and im using a obd2a to obd1 conversion harrness running a chipped p28 tuned based on my b20V spec. But my engine dizzy is acuttly and obd1 dizzy plug into a obd2a is this what is affecting it?
I have no check engine light the car run super good when i drive. only when im stop and idleing drop
that where my problem is.

I adjust the tb screw now it idle at 800-900 where it is spouse to be but i can still see the idle drop to 750-800 constinly and it can feel the engine kind u know shake sputter. it can't be no back fire or anything because when i give it gas i rev up find no shaking stall, pop or nothing or nothing so im thinking it a sensor some where or it is the obd1 engine dizzy i put on. it try 3 ecu out and it did almost the same.
