Re: G23 Badly missing obd1

the square thing is ur ignition control module. Those go out on there own sometimes n can cause missing as well. U can change them but its kind of tricky. I have a spare ICM laying around if u would need one. lemme kno. The dizzy i pulled it out of worked when I pulled it
