when i first bought my 90 formula i found the rpo sticker in the console...i decoded it and now i've lost it!!!!!! is there any other way to get all those codes back from on the car or is that sticker the only way of getting the codes.....any help would be appreciated...thanks guys!!!

 

Since you Formula is a '90 your local GM dealer parts dept may be able to pull up and print the RPO list using her VIN.Another option would be Pontiac Historical Services (PHS) but they have had problems as of late.Do a search on here for their website and there may be a phone number to call.Hope this is some help for you.
