following some ticking/rattling issues (see : http://www.alfaowner.com/Forum/alfa-...-problems.html
) that eventually helped me to solve a mixture problem by soldering the pre-lambdas (thanks MGG !
), I now need a new "maniverter" for the 2.0 JTS.
I've looked around and it seems that options are not endless :
1/ buy a new genuine one from Alfa : expensive
2/ buy a used one, but genuine Alfa
3/ buy an OEM version that can be seen at around 350 Euros - looks like people had some problems with low quality
4/ buy a sports cat : found an expensive one for the TS, but none for the JTS
If MOT would not be a problem (hypothesis), what about the following 5th option :
cut the maniverter at the cat locations, clean everything, and weld back
Question : are the post-cat lambdas only used for monitoring the cat's health, or are they used for air/fuel mixture purposes as well ?
If not used for mixture problems - and if MOT is not an issue - is there any trick to fool the lambdas and let them believe the cat is OK ?
