Hi my cx30 is a 2020 gt sport mhev auto awd. I am getting an emission error relating to a lean mixture. I have done the usual ie. Changed the spark plugs, cleaned the MAF and oxygen sensor. My tickover is rock steady, my engine very smooth and I average about 45mpg. Most of my runs are local rural about 3 to 10 miles, very rare for a long run. I service my own car which is very up to date. My battery is very good. It is the engine icon which dims. Help please?

 

uh ... Welcome to the forum


why would you start a vote for thread instead of the help me thread in the area pertaining to your Mazda model and year of the forum??

When you do, I will be more than happy to recommend and advise...

At this point I can only say you are wasting time and money changing unconfirmed problematic parts based on very limited diagnosing information.

 

Thanks but not very helpful. Only wanted to ask for help but doing that seems difficult. Maybe some instructions could be useful

 

Perhaps take my advise and start a thread in the proper area?
