i have a 1995 pontiac grand am gt with a 3100 L82 in it. my question may sound dumb, but im not fond of the OBD stuff. What OBD is mine? ive been told 1 than told 1.5? any links anyone could point me towards to possibly upgrade it? what all necessary parts ill need to upgrade? i do apologize because i know you all have prolly seen this question a billion times. Im asking you guys because you have been my auto consultants for awhile and havent let me down yet. I was at the junk yard today and was lookin at a 3400 in a Impala and asked a dude if he knew what i should do, he told me to take the 3400 computer and hack it up and me re-wire it in. Sounded kinda iffy to me......thanx a ton guys
