Wasn't a problem before this recent mend.

Could it also be a need to replace the MAF sensor?

Wiggling the little wire harness connected to it seems to cause the rough idle.

Is there a best method used to diagnose this and apply a fix?

P.S.: Is there a best place to source the $en$or if it is in need of replacement?
