Question about 1997 Oldsmobile Bravada
I have had the spark plug change, new ignition cap, new plug wires, newfuel filtter. The coil was found to be OK. Problem isgetting worst. I have added cleaner in gas for fuelinjectors. The check engine light come on around 60 MPH and thenresets in about day.
Ok guys, let's fix these things here!
Just went through this myself, so do the following:
Go to your local parts store and buy a Haynes Repair Manual.
You need to read the book first, learn how the ECM (Electronic Control Module) works. You'll see that there are alot of sensors and components that make up the fuel emissions bologna.
The nice thing about this system is not only does the ECM control all electrical functions, it also trouble-shoots it's self. When a component or sensor goes out, the ECM stores a code for that event in it's memory. You can use the Haynes Repair Manual to put the ECM into diagnostic mode and thus read any codes present.
So, all that's left is replacing what the EMC tells you too! :) Good Luck!

I doubt it is a speed sensor. It is in the transmission near the passenger side cv axle. Have you scanned it for codes? You can do it with a paperclip.

Could be the other coil pack. Be sure to check and clear all codes stored.
