Hey, I got a 99 Lumina with the 3.8L.
Recently my Engine light came on. I went and got a book from my local library. In the older GM's you could jump the com plug and read the flashes of the engine light. There is nothing of this in the book. All are letter and numberic codes.
No where around here lets you "loan" a code reader.
So is there a way to jump it and read them yourself?
Or am I SOL and need to get it into a garage?
Thanks for any help.
