MAF connector

[jamesmc]

I have read that improper oil change procedures can have an effect on MAF sensor connector in some vehicles - what kinds of procedures are considered incorrect and what are the implications?

What vehicles are affected by the above?

i dont know exactly what vehicles, but i assume it is because of getting oil on the connector, probobly from unscrewing the filter and having the oil drip on it.

thanx, i assumed it was something like that - am trying like hell to diagnose my hesitation prob - thinking maf again becuz when i unplug the connector it hesitates at exactly the same rpm. maybe a bad ground? see original post under 91 stanza hesitation at 2500 rpm.
