i have recently changed my engine wiring harness,my 2 fuel pumps with filter, air mass sensor...the car is still not performing as it should... it intermitently misfires(some days doesnt do it) and wont rev over 4000 rpm ie when kickeddown wont perform like a five litre v8 should... the car is a 1994 s500 coupe any ideas..... cam sensor/ crank sensor ht leads etc it is very offputting as this is my first merc, previous car bmw 840i which won on performance hands down..... i was told the merc should outperform the bimmer by far...could any one help me as i have already poured a fortune into the car..... regards
