i am having an idle issue on my 90 1.6. my electronic idle valve works fine however is not getting the command signal from the ecu, all wiring looks fine but ive been to lazy to actually get the wiring diagram and check continuity. but if anyone has a 1.6 i could snap in for a few minutes to check and see if it solves my problem i would be happy to meet up with you.
btw i live in fort worth and work in euless
