Unfortunately replacing the coils did not solve my P420 problem and I had to spend almost $1000 today getting my catayst replaced. I think the coils had been bad for so long that they plugged up the converter. BUT the car ran noticeably better after I installed them, and my wife says it runs even better now that the converter has been replaced. THANKS!
