Hi there, I am Cam. Can i get your first name please?This sounds like a weak ABS sensor. When it gets weak, it can send a signal that mimics the signal of a stopped tire so it makes the traction activate. This will not usually set an ABS light since the sensors is still physically intact and the resistance is to spec, but since it drops off, this is the result. The way to find it is watch the valving on a scan tool and see which are activating. given the age, have you replaced any front wheel bearings yet?This is not related to the tire system. That system uses the remote control door lock receiver which is in the passengers door switch. The valve stems have the sensors in them.Also to get the traction activating does not at all include the throttle body. Throttle issues would not make the pedal pulsate.
I can understand Eliot. With this issue, the hard part is determining which one is causing it. if you cannot find any play in the wheel bearings then you may try turning sharp in a parking lot either way and see if one way makes it act up more. If this does not change it, then if you can do the work yourself, try changing one front hub. Because they are not side specific, see if the one corrects it. If not, put it in the other side and re-evaluate the issue.
Ok, that tells me that your left wheel speed sensor/hub is weak. In a left turn, the left wheel is going slower than the rest and that is made worse in a left turn. I suggest you replace the left front wheel bearing assembly.
Yes, that fits. This is because its disabling the traction control system.
They are about 300 each and about an hour to change. I would only do the left side.
