SUZUKI told you to disconnect the pink wire??????
Whats the difference where you disconnect it? It will still be disconnected. How did it run through the other gears.
By placing your tps to its lower setting on the LCD will make the ECM believe that the throttle is closed further than it is. (i.e.-2 % throttle) This may allow a leaner idle--you could also remap the idle with the YOSH box, why did they not recommend that since Suzuki let Nippendenso design the box to get around emmissions?
Problem is using the LCD display is crude and does not give you a good indication of how far you have gone.
The P Commander will let you see this (throttle position)when connected to your personnal computer or laptop. You could also measure voltage-numbers are given in the manual.
I think none of this should be needed however since I have obtained a linear response from the throttle with the TPS set correctly (0% throttle at idle) using MICRON full,PC2,airbox mod, BMC filter. MUCH better than stock.
Keep looking for another problem.
Use a load step Dyno with a exhaust gas temp and CO measurement especially at the rpm and throttle position of the problem areas. Check all of your sensors, which will take you an afternoon.
