The traction control ...
Let me make a follow-up to my original post -- I sent that before I should have.
The traction control system (let me abbreviate it TCS) has two priority levels, traction and directional control. At low speeds, if wheel slip is detected, it will maximize traction. There is usually no torque management occuring at low speeds, just brake modulation. At high speeds (above 50 mph), if wheel slip is detected, it will maximize directional control. There is no brake modulation at high speeds, only torque management.
The TCS engages only when the system detects one or both front wheels is losing traction. When excessive slippage occurs, the system will engage.
If the Eldo in question was traveling above 50 mph, it is possible that torque management was engaged. For the record, it can cut fuel (the spark continues) to as many as five of the eight cylinders. I can feel the torque management when I'm racing up or down a curved interstate entrance. If it's wet, I can feel the front of the car push a little bit and the tone of the engine will sometimes change and I can feel the front of the car pulling back in the direction that I'm steering very slightly.
If you are going fast (above 50 mph), this may be the cause of your engine symptoms. If at a slower speed, I would guess it's something else. It just doesn't sound like the TCS in action.
When the brakes are applied, it'd sort of give the same feeling, but it'd be real apparent that it's modulating the brakes because of the rumbling of the ABS equipment. It's possible it may be something in the transmission. Have you pulled the codes from the vehicle?
autolite copper clugs for 3 reasons: one they will work with the car, 2, they were cheap and i was short on cash today when the car started stalling from the bad plugs, and 3, i run them in everyhting and never had a problem with them.
I wonder if the constant use of traction control somehow overloaded the brakes and caused the engine to start cutting fuel. And somehow the lack of fuel caused the spark plugs to overheat and fail? That's interesting...sounds like severe damage to them if the insulators were cracked! Good call on replacing them. Elwesso's right -- they're platinum and should last essentially the life of the car. Mine are almost 112k miles old and the thing still lays waste to anything short of newer V8 Mustangs and Camaros.
Speaking of which, I saw some ghettoed out '96 Mustang today...V6 model. Had the Altezza something taillights and wheels. His license plate said XTREM96. After I wasted him from one stoplight, I wanted to roll down my window and ask if that stood for "extremely slow 96".
