Took the rex to be mot'd and failed on emmisions, told to get a diagnostic carried out : no one round here will do rotarys 10mins search on the internet recommended injector cleaner and a good thrashing. at first didnt think it would work due to the results being over double the requirement. anyway £3 injector cleaner and 1/2 a tank and it passed with flying colours. saves me the £1800 mazda quoted me for a new cat. Just shows what 10mins research can do!!!!

 

Wow, good results!

Congrats!
