What is your question?
Hi: I have a 2002 Stratus 2.7 engine. Today kicked out a PO420 code, bank 1. No others. Talked to several local mechanics who all referred me to "Joe" who they considered to be an expert. I wanted to see if he could pin down if cat was bad, or bad O2 sensor. His normal diagnostic charge is $90 but he refused to do it, says would waste my money. He says this vehicle/engine, I have to go to dealer and have both converters and all 4 sensors replaced with factory parts. Says for this vehicle/engine, after market parts won't work. What say ye ? thanks, Mark

It's not a rocket science to check a catalytic converter efficiency when you have the right tools and knowledge. You are in the wrong circle of mechanics / shops. What he told you is the same if a doctor would tell you: Don't waste your money on EKG, you need a heart valve replacement. You would believe him, right? I wouldn't use aftermarket cat. converter on any vehicles, did it before, never worked, won't even try it again. However, you need that diagnostic performed by a real tech TO SAVE money. Zee
ZeeTech: Thanks for quick response. He is not saying he can't diagnose the problem. I think what he is saying by "don't waste money on diagnosis" is that based on his past experience with 2.7L Stratus multiple times, the only sure way to restore it back to specs that the control module will accept as good is to: 1) Replace both converters and all 4 o2 sensors, and: 2) Replace all with factory parts only. Note that he's turning down the work and telling me to go straight to a Chrysler dealer. The guys in other shops tell me he's a master mechanic who has won multiple diagnostic competitions. They take their problems jobs to him. I've never dealt with him personally.
