After decelerating from 40 to 10-15mphish to make a turn the car likes to (occassionally) quit. I coast over to the curb and shut everything down and restart. It will run fine after that possibly until the next day +/-. There is no real pattern other than it only happens when turning and right more than left. Highway driving is OK. Year is 1989.

I appreciate the input.

Dondas- last year about this time you did in fact help in the diagnosis of my 500 SEL//ASR Fault/ it was and still the electronic acceletator actuator. Thanks

 

Clean the "butterfly" of the throttle body. If problem still persist, you may need to change the throttle body.

also check all the vacuum hoses for crack, loose fittings and so on...
