Title: 71 280sl won't accelerate
Post by: premier on June 27, 2017, 00:48:43

Two wire vinturi on side of throttle when wired up the car won't accelerate as if no response from gas pedal. If 1 wire is removed then the car seems to accelerate just right...I'm in need of help with this concern if you have any experience with this system. Any advice is appreciated.

Hi Premier,
Welcome to this forum.
The 'two wire vintury on side of throttle' is actually a sensor providing throttle position to the auto gearbox.  That switch has nothing to do with acceleration.
 HOWEVER, if you mean the auto box is slipping and therefor 'no acceleration' then that switch must be reset.
The switch provides throttle position info to the auto gearbox in order to provide a certain amount of slip when selecting D or R. As soon as the throttle is opened a little, the switch will open to allow normal acceleration.
Rest the switch position to open sooner. There is a lot of info on this forum.
Regards
Chris
