How can you convert the wires ?! I check out the 2.8 wiring and 3.1, i try to plug the different wires for the 2.8 at the same place that show in the diagram but it doesn't work anymore !! plz help
You would need the egr adapter/pipe. The eprom for the computer, also the connector as it is different and you would need to do some rewiring- change a few pinouts on the ecm side and redo a few wires in the engine bay as the egr wiring is tied into a couple of sensors. Basically get the good diagrams (helm/mitchel-shop manual) and the valve and the pipe/adapter, and connector with leads.
Come on!!...i know what is egr valve. You have a vaccum on your 87, that doest break!
History about "the piece of shit"
1- the gasket ON the egr valve was leaking, impossible to change
2- the base was cracked(not at the installation but when the mother*** unstall it at junkward), another leak!
3- No more power on(check engine and tested)... :roll:
4- base was cracked once again !!
Now i'm very tired !! All of those are used at junkyard, for a new one its 500 CND box !
PS: GM wiring harness is the most complicated wiring i never seen !!
