Well We did a flow test and found that the downstream converters are both restricted (clogged) which lead to a failure(meltdown of the main manifold converters) which lead to the egr sensor burning in two by superheated exhaust gas. Bank 2 converter went bad two year agO. I didn't realize then that the bad converter sent material downstream into the other two converters. The cause of todays failure. So I am going to replace the converters all 4 at a cost of over $2000. Thats if I do the Job myself. I know now after I get the converters down I have to run an O2 sensor balance test. I'll be looking for any antifreeze leaks from the engine as I tear things down. Plus I'll be changing plugs and a wire set for good measure. I am going to take it in for a complete go thru for the sensors on the engine. I want them to check for a overfuel or under fuel condition too that might be cause by a slowsensor. I am going to have them check the function of the fuel inJectors for a sticky on or failed one. That also can cause premature cat failures. I hate these OBD computer systems. Its almost impossible to check all of what might maybe or could have gone wrong. I hope in the future someone reads this and can lean form my minor but costly mistakes. The total cost I am looking at is around $3100. For a car thats worth only $3800 to $4500. It might go to the yard I havent decided. The car is worth more in part than the repir LOL. It has a really nice body and everything else is now prefect on it.
Thanks for the help and I appreciate the advice thanks!
