Rough idle sometimes at startup
So just this week every once and a while ill go to start the 350SDL and itll run rough for a few seconds and then go back to standard idle and regular rpm. Since this model is electronic idle controlled I assume its something with the idle control? I did notice once or twice tonight the car ran rough for almost a min and the tach was dead even after I revved the motor and the ABS light came on. Need suggestions, Im heading to 1000 islands tomorrow so I would like to get this resolved asap. Thanks!
