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.

 

check for vacuum leaks and Idle control valve. im pretty sure it have nothing to do with the dizzy

 

check that but still the same no leak

that's the only thing i could think of also that would cause the idle to act like that...you should double check it...

 

Op: does the car do this as soon as you start up? Or does it go through the "warm up" phase first?

 

figure out what was wrong with the car yet?
