560 sel hesitation

[demeterial]

hey ladies and gents Ihave a 91 560 sel that was hesitiating from stop lights and idling rough for about 5 sec and then would smooth out perfectly well.. I found a loose wire on a temp sen sensor of some sort going to the radiator.. reattached it the car is missing so much less now.. Ill get it tuned up with new rotor cap plugs and wires.. and that should solve the slight misses and hessitation ..
Thanks
