2006 Mustang Surge
It started with driving about 45 mile up the highway then coming to a red light. When the light changed and I put my foot on the accelerator it did not respond for a few seconds then lunged forward without changing the pressure on the accelerator. As time progressed there was no longer a pattern other than stopping at a red light for a few minutes. Accelerator, no response, lunge. What causes this and has anyone else noticed it. I have found it on old ford ranges and probes but not mustang.
