Heres my problem eml is on car drives ok no loss of power or anything had the code read and my mate sent me the link for the code

http://wiki.ross-tech.com/wiki/index.php/17831/P1423/005155

Anyone got any idea what this could be

It says it on the link. Check the issues it suggests it could be. Fuse, vacuum hose etc.

Not being patronising, trying to help

this is normally the rivets have failed in the secondary air pump!!! have a look under the car at the very front there is a large pump that is there for cold start emmisions it more than likely is broke but its fixable check out he guides on here

its not an issue you can still drive the car as normal

rivets are best replaced with nut and bolts or do away with it altogether again guides on here do a search

good luck any issues pm me
