SVT stalling and cleaning your ground connections
Over the last few months, I've been refreshing the SVTF (It has 92,000 miles on it). New plugs, wires, cleaned the MAF, cleaned the air filter, new fuel filter, replaced the VCT solenoid, new timing belt, etc.
Anyway, the car has had an issue familiar to many SVTF owners, stalling when coming to a stop. Over the last few months, it's been getting worse and had gotten to the point where I could pretty much count on it stalling at least once per day and come close to stalling a few times per day.
One maintenance item I had not gotten to was cleaning the ground connections by the battery. I've owned two Mustangs, two Merkurs and two Focuses and I've always found that computer controlled Ford products can be sensitive to how strong the ground connection is in the wiring harness.
This past Saturday morning, I set about cleaning the three ground wires attached to the inner fender well just to the right of the battery. I used a wire brush and cleaned both the connectors and the bolts. While I don't believe this to be a cure all, the SVTF is running better, has a better idle and hasn't come close to stalling in two days.
So here is your Top Gear top tip...
Clean those grounds and maybe you won't have to be embarrassed at the next stop light when your SVTF decides to take a nap.
