Can a faulty DPFE sensor cause my lifted 02 f150 to wobble violently?

Question

I have a lifted Ford F-150 with a "death wobble" and was hoping a faulty DPFE sensor would be the root problem. I've already replaced the front end and it still shakes going down the road

Answer 1

No , a faulty DPFE only opens the EGR by using exhaust back pressure, the death wobble are most seen on Jeep vehicles or any vehicle,  when a 2 wheel drive vehicle is lifted and a off road tire or 4 wheel drive tire are installed on a 2 wheel drive vehicle. If your vehicle is a 2 wheel drive or  rear wheel drive and is not equipt  as a 4 wheel drive and the vehicle is lifted and 4 wheel drive tire or off road tire are installed you can be sure it will have a death wobble.
