w114 1971 250 Coupe Full Speed Ahead !
Greetings to All !
Am looking for some insight as to the issue behind the acceleration problem with my Coupe. It has taken to jumping full throttle whenever it so desires. Whether it be at a stop light or at a low speed. The only way to stop the vehicle is to throw it into park and cut the engine. The accelerator cable was replaced in Jan. 2006 when the car went full speed ahead and would not stop until I cut the engine. No problems until a year ago, when it acted up three times, was fine until last week. Now it is kicking a fit randomly and frequently. Have brought it to three different mechancs who can find no fault with the accelerator cable or linkage.
Am curious as to whether anyone else has experienced anything similiar or may know what else could be contributing to the acceleration. A friend mentioned perhaps the fuel pump is about to go and is tossing extra gas? Does this make sense? Or the carbs or acting up? Any input would be appreciated. Going to garage #4 on Saturday.
Thank you for your consideration.
