How do I fix a fuel to rich or a fuel to lean issue in my LR2. For a while the check engine light would come on and off every few months and when the computer is scanned it returns the code as too rich or too lean. Any help would be appriciated.

 

What are the specific error code numbers?

 

Clean your MAF sensor carefully with dedicated MAF sensor cleaner and clear the codes? But, yes, you should really post up the codes here for clarity.

 

I agree with THOR clean the MAF.

The next thing to look into is the fuel pressure sending unit.

Let us know what codes you have and we can provide more suggestions (as FLYBD5 pointed out)

Thanks
