Did you disconnect the exhaust manifold or catalytic converter? Exhaust leaks can cause P0420 good luck _____________________________ See you down the ROW 1994 Accord EX (in reply to has) Post #: 2

I had this on a 99 Subaru Forester and after some time monitoring the rear O2 sensor output signal (which indicated bad converter), I replaced w/ an Eastern Catalytic Converter ( a bolt-on unit). It has cured the P0420 for over 1.5 yrs now. Another "fix" is to fool the ECU. You can do this w/ a mechanical spacer for the rear O2 sensor. See attached link. http://www.scoobymods.com/forums/showthread.php?t=5468 Oil leak may indicate need for a new oring on the distributor key rotor that connects to camshaft. This can leak and oil will be running out of cylinder head at the distributor. good luck _____________________________ See you down the ROW 1994 Accord EX (in reply to has) Post #: 4
