Got a lambda sensor error code on my 180bhp AJQ engined 1.8TQS, but is there only a pre-cat sensor on this engine, or could it also have a post cat one as well.
I think early cars only had the pre-cat. Can anyone confirm this?
Don't want to buy the wrong one as I'm gettin some lean running at higher revs and burnt out a set of plugs. Ars3.
