89 XJ Renix, AX15
I have had problems in the past with passing emissions testing and had the Cat and O2 sensor changed about 4-6 yrs ago.
I will be changing the O2 sensor and have new plugs, TPS, CPS (if those even matter), fuel pump and filter, injectors and air filter.
Anything else anyone can think of would be appreciated before I spend the money to test it then have to get it worked on.
PS
To replace the cat is there welding involved? It looks like it to me.
