MAF & Faulty Ground/Problem Found?

[Funmart6]

How would a faulty/bad ground affect the MAF???

Some of you may know of the problems I have been having with my car/engine not running correctly and it has had all the symptoms that would point to the MAF not working correctly.
Well, I found recently that the fog lights, (that I installed on the car many years ago), were not working. I checked and found the power wire, which is connected to the battery's positive side, was broken at the connector. I replaced the connector and the lights still would not come on, and I was going to just remove the lights and be done with them. I had the ground wire for the lights connected to the battery on the negative side, (maybe I should not have done that), but anyway, I found the ground wire was broken also. I replaced that connector and grounded it this time to a location on the body of the car. I have driven the car for a few days now without any problems whatsoever. I have driven the car slowly and it shifted perfect, and I have driven at WOT and it shifted perfectly as well. Did I possibly fix the problem with the MAF just by relocating the ground for the fog lights? I know it does sound crazy but I am just happy that my car is back to running perfect again, and as a side note my fog lights seem brighter now also.
Anyone ever experience something like this before?

electricity is like water, it flows the path of least resistance. I've had simular issues, and even on a car that acted like the computer was internally shorted out, all because of one chassis ground. A weak ground can cause all kinds of odd running and operational issues...especially on the multiport fuel injected vehicles. Usually my first step when diagnosing a problem car, is to check the electrical output of the alternator, state of the battery and clean the major grounds (block/battery/frame/firewall).

Thanks, I really just stumbled across this. If my fog lights had not quit on me I would have never known. My fog lights are also wired into my parking lights, and therefore tied into the electrical system if that makes any difference. All I know is, my car feels normal now and moves out really quick when I get on it, no more bucking around, and I am enjoying the sound of the V8 once again.

One thing I did on the SHO was to connect all the body ground under the hood together with copper. I connected some wire for all the grounds together and this all landed in a ground block that the battery and engine grounds were tied to also.
