For a year now my stang has been running like crap! Surging, hesitation, bogging, pinging just to name a few things. Thanks to everyone on these boards I have finally fixed the major problem. Part of the problem was my O2 sensors which I replaced a few months ago and that seemed to resolve part of the problem. Then I decided to check the MAF to see if that was the major culprit. By my surprise it was. That thing was dirty. I cleaned it up with electronics cleaner and q-tip and I tested it out this morning and now it deffinitely feels like I have a V-8 Mustang. Better yet, I think it runs better than when I first bought it. It is amazing how those little wires or even a sensor can screw everything up. Now if I would have only done this a loooooooooooong time ago, would have saved myself a lot of frustration, thanks again guys! Now I can start my MODS!!
