i have a check engine light that turns off at 85 mph in 5th gear (about 4000 rpm) maybe a little higher)). its an 86 NA. i was wondering if that would be my tvis. dont mean to hijack or anything, but i have been looking for an answer to this problem. my cooling system is bled and temperature and idle are ok, but i still have a light on. i have cleaned all air system parts when i installed my weaponR short ram intake. i have an aftermarket exhaust too. where should i start? O2 sensor?
