Help failed emissions
#4
Like Cully said, need to get it on some diagnostics to give some indication of what's going on. Unfortunately when it comes to mixture regulation you don't always get specific codes that point to one thing. If you haven't been getting at least an intermittent engine check light I'd be surprised.

Could be one of the new parts (lambda & coolant temp sensor) are still the problem if you haven't fitted good quality parts. (Learnt from experience there!!!).

OR, could be MAP or air intake temp sensors, which also input to mixture regulation. Previous cat was prob damaged by over-rich running. (On mine it was burnt thro n half the cat internals ended up in the back box!).

OR, could be loom supplying any number of sensors.
