Recently i had plugs change, one of the plugs,counting right to left facing the engine the second plug has a some what black soot,the mechanic informed me that the airflow meter needs a rest, or a change.What are other negative impacts do an assumed airflow meter have?

Sultaan see now... you didn't allow me get to the root of his issue yesterday. Now he's bringing them in piecemeal.... Well over to you.
But indegene you will be doing yourself a big favour by starting from the beginning.

Is actually the mechanic that need to be changed cos what he is insinuating doesn't make sense .
Presence of black soot indicates rich mixture and what diagnosis precodure does he indulge in to be able isolate out the MAf .I am sure after changing the MAF and the issue persist ,the next item will be the ECU (Brainbox ) .
Try to engage a recommended professional mechanic to diagnose this issue for you to avoid expensive trial and error change of parts .

Great go and apply it. You are not intelligent enough to know my goal of asking you those questions. And that you can gloat over some YouTube videos shows that you are a far distance from understanding how cartalk works.

He has refused to clearly outline his problems. And like the Honda hooked at ladipo he's been asking in piecemeal. Now that I told him that he should narrate his problems from the beginning he's gloating over some YouTube video.
