Hi I have just downloaded the following codes from my car I think it is the Lambda sensors that are at fault but if you can help that would be great. The car is running badly at tickover (misfiring) and lacks power ( it runs out of steam at about 135 mph were it should do 155mph)
P0300
P0301
P0302
P0303
P0304

P1316

P0420
P0430

P1000
P1113

P1647
If I am right and it is a Lambda sensor which one of the four is it.
Thanks for your help.
