Can I replace computer myself on 99 gmc suburban
has 2 pages of trouble codes, passes emissions test i Colorado. Starts to miss
badly, qualified mechanic cant fix. Only thing he can come up with is might
need computer, must be done by dealer. I found at parts store computer for
less than $200. Found on internet, should be plug & play, is that true?
Yes you can change your self,if the computer number,s match,if they don,t match you will have to have dealer program it.
