I've had my 1998 3.8L V6 Mustang for almost two years now. For the past month or so my car has had a rough idle and it occasionally stalls. However, when it stalls, I will turn the key to the off position and then I will restart the car. Most of the time it will run fine for a while before it does it again.
I DO NOT HAVE A CHECK ENGINE LIGHT ON...
Recently, within the past week, I've replace my spark plugs, plug wires, and fuel filter. I've also tested my coil pack with and ohmmeter and all of its ports seem to work fine. I have also done a visual inspection for cracked vacuum hoses. My PVC valve has an old corroded hose that I plan on replacing tomorrow.
I've considered cleaning the MAF sensor, but I've been told that I shouldn't mess with the sensors if I don't have a check engine light on.
I need some pointers. I've done the cheaper maintenance and I hope to not spent a boatload of money trying to figure out what is going solve this frustrating mystery.
BUT, when my car runs, and it isn't idling funky, it's obvious that the car is running better with the new parts.
