Alright, I've had this surging issue with my DA for a while know and I've mostly ignored it. However, now I've had enough and I want to fix it.
The code that eventually gets thrown is #9 Cylinder Position Sensor Circuit.

Now the FSM talks about checking continuity and wiring, which I plan to do on Sunday when I'm off. But is there not a sensor the I can replace for this? Or do I need to replace the Distributor? (it seems fairly new to me).

93 GS-R.

 

code 9 would mean the sensor in the dizzy is bad. you cannot purchase that sensor separately, you must purchase a whole dizzy. i would recommend trying a junkyard dizzy if you are worried about money. try ebay or another online retailer for a distributor. no point in spending $400 at the dealer when you can get the same thing for half as much or less.

 

Thanks, I will see what I can find.
