Use the SEARCH feature here on Zilvia.Net to find a link for an 89-90 Factory Service Manual. Once you download the FSM, read the section on Setting Idle. If I recall correctly, you HAVE to disconnect the TPS harnes to adjust your timing & idle. It sounds like you're adjusting the idle properly, but you might also have to readjust the timing. Your motor is supposed to idle at 750 RPM with the TPS disconnected. Download the FSM & read up on the Setting Idle procedures. The FSM will clarify all your questions...
