My Jeep began experiencing a death wobble going about 65 mph . When driving at 65 mph and went over a bump on the roadway my vehicles steering and suspension began shaking violently and almost caused an accident. Anytime the vehicle was cranked up the throttle was elevated and stayed elevated till for 10 mins and you can not drive for 20 mins because the throttle would stick wide open and unable to lower . The exhaust has a backfire upon acceleration as well. The exhaust system is ran underneath the gas tank which I believe is a hazard . There is a ticking and knocking noise in the engine as well.
