hi everyone, my '93 sl500 konked out today top of gravel hill south of croydon surrey just in front of the tram tracks. heck! i had to roll backwards to get away from the trams the size of small trains! ive been experiencing a lack of pulling power recently. i warm her up put her into drive and off we go. but , as my journey progresses every time i stop it wants to go but cant. and then it does. its like someone is tugging at your shirt as you want to run off. it doesnt jump. i checked the fluid level on the stick when its hot and it looks like theres plenty there. when i broke down today i struggled to get up the hill in question. the car restarted but as soon as i put it in drive she shut down! in the end i called the brake down man. by the time i got home i was able to reverse off his truck and drive the car into my slot outside my house. obviously it had cooled down enough for me to do this. ive also been smelling a burning oil as if something had been dripping onto my exhaust and when parked leaving a oil deposite on the road. can anyone help me with some advise. many thanks jw.
