i kno this is probably a stupid question guys but how do you check codes on the 1j supra? i've never pulled a code on anything besides obd2. i was drivin the supra today and after beating on it for a few minutes the check engine light came on. would the idle air speed valve have anything to do with tht? cuz mine is currently not hooked up correctly. after i turned it off and the started it back up the check engine light was gone.
