0420 and power drop
« on: 01 August 2011, 19:24:12 »
3.2 has been running great for weeks. Driving tonight, eml came on, logging 0420, bank 1 cat below efficiency.

Related to drop in power?

Could the fact my nearside cat has the lambda relocated, but offside one has not, cause any problems?

No other symptoms just power loss.

I'd say it's a red herring James... I don't recall anyone ever having a drop in power with cat efficiency codes

Whatever it is... I didn't do it

Back when I used to get 0420/0430 codes (prior to moving the lamdas), I never noticed any difference in performance when the EML came on.  :y
