2004 Jeep Grand Cherokee. While driving at any speed vehicle jerks sometimes worse than others at the same time speedometer and rpm gauge drop and come back on engine light blinks and goes off. Taken it to dealer many times they told me nothing is wrong after three times they replaced computer and sent me on my way but it did not solve the problem and a year later replaced computer again as well as throttle position sensor and still did not fix problem. This is my only vehicle and I need to have the problem resolved.
