MiaNoir Posted May 30, 2008 Report Share Posted May 30, 2008 I couldn't find a tutorial for removal of the PCM in an 04+ 3800 vehicle so I decided to make one here goes. This is not an official GM Approved way but it's how I did it and it worked. You will need: 1/4" Nut Driver 1/2" Socket and driver Steps: 1: Pop the hood. 2: Remove the fender brace by removing the three 1/2" bolts. 3: Locate air box 4: Unclip the airbox, remove the filter, and Unclamp and remove the MAF sensor using the 1/4 nut driver. Place out of the way. 5: Remove the filter housing by unscrewing the two bolts holding it in place. Place out of way. 6: The PCM is located inside the second portion of the airbox. 7: Do whatever you needed to do. To Reinstall the PCM: 1: Perform steps 2-6 in reverse order making sure to put everything back where it was. 2: Close Hood 3: Wash hands. After this your hand probably look like this. 4: Start car. I hope this helped somebody and I realize it's not perfect, maybe it cleared somebody's unspoken question if they had one. ~Brandon Quote Link to comment Share on other sites More sharing options...
