156 V6 MISSFIRE
Discussion
Just had a Hayward & Scott exhaust system fitted (race cat and single back box, What a sound) 72,000 mile service + power steering pipes and new standard air box. What started as an intermitant missfire when warm has over 4 days become continuous. Any ideas?.
Did think it could be water after washing off oil spill from pwr steering but all plugs and connectors are dry.

Lambda sensor would seem likely. This sensor is in the exhaust catalytic converter section, and may have had its wiring damaged at time of change. Either that, or possibly excess heat was needed to remove it from the old cat, which damaged it.
They tend to be a consumable item on the V6 anyway, as does the air mass sensor. It is generally accepted to change them both if you suspect poor performance. They seem to deteriorate over a period of time.
