M-Class 430
 

i have been working on a m-class mercedes for the last two days. its a ml 430 so that makes it a v8! i drive it down the road and the car goes into emergency mode (cuts off n/s bank cylinders 5.6.7.8) ive put the computer on it but it just comes up with
misfire detected cyl5 the same throughout 6.7.8. ive changed the plugs and the leads on the near side bank. could it be the air mass sensor? i have one coming this afternoon. any help would be appreciated. thanks. *carlo* (ssmotors 01932 821555 uk)
