Yes its back again,but this time its throwing up code 0430 as opposed to 0420This was reset thursday,and been fine till today.Any ideas anyone.By the way,must say wellung your a top bloke for resetting it,yes you can guess whats coming next,any chance of round 2 mate. LOL :y.

0430 relates to the catalyst operating below the efficiency limits, as is 0420. It is the other bank that has generated this code compared to the 0420 code.
These codes relates to the pre cats on both banks, a common ailment of the 3.2 and 2.6 engines.

Welcome to the world of 3.2 Precat failure.... nothing to worry about, car will fly through emissions test as main cats are plenty good enough to do the job.

Would it be ok to rip these out and is it a big job?.

No problem Mark, it was showing both 0420 and 0430 when I reset it last time, it's CAT efficiency on each bank, need the lambda's moving back like we spoke about. :y

No probs, gimme a bell before you set off just so you know where I am ;) :y

You'll get used to the Emissions lamp coming on all the time and give in resetting it after a month or so!
My last 3.2 used to illuminate the lamp every 2 - 3 days!

This is probably the kiss of death ..... but mine has only come on twice in a year :) Up in the mountains of southern France last August, when it had been driven pretty hard, and then early October, both were 0420. Other than those ... nothing :)

Same with my 2.2 :-/

The 0420/0430 is common when the pre-cats start to fail, simply (well not so simple but...) moving the pre-cat Lambda sensors to just behind the pre-cats normally cures it for good.

And me! >:(

Nothing to do with me but THIS (http://cgi.ebay.co.uk/LAMBDA-PROBE-WELD-IN-BOSS-AND-PLUG-SET-6-FREE-POST_W0QQitemZ330326837461QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item330326837461&_trksid=p3286.c0.m14&_trkparms=66%3A2%7C65%3A2%7C39%3A1%7C240%3A1318%7C301%3A1%7C293%3A1%7C294%3A50) is what you need to get welded in between the cats and use the plug to seal the pre-cat hole. It needs to be a pressure tested airtight weld though or it'll cause more problems come MOT emissions time :y

Used to have the same problem, til Mark got his hands on the car and thats now fixed pre-cat lambda's gone, no EML problem now :y, don't think he moved them back, pretty sure he removed them completely ::) - pretty sure Bob.dent has the same probelm with his.

Now I'd be interested in how that works :y
