[Solved] Maf sensor cleaning, ltft values closer to zero

Topic starter

Pre MAF sensor cleaning I had LTFT values of 7 to 12% on idle.

Post cleaning it's around 0 to 3%. 

Why is this a good thing? What problems might I have prevented? Thanks

Why is this a good thing?

because you want the correct air/fuel mixture. A lot of engineering and effort goes into getting this exactly right.

What problems might I have prevented?

Most of all, poor fuel economy and reduced engine power.

(plus a host of other problems cause by incorrect mixture like running too hot, wearing out the catalytic converter, carbon buildup, etc.)
