Over filled my oil the other day (1999 mondeo 2.0lx) all though i didnt realise at the time, until i was on the motorway and had clouds of smoke behind me. I was only out in it for about 10 mins and i have since drained the excess oil out (now on the max mark). just for good measure i changed the spark plugs and air filter. I now have a new problem....the car judders under acceleration so much the the steering wheel shakes, it aslo idles a bit erratically. and when im stationary and blip the accelerator i get a pffffft noise briefly. i thought maybe the plugs were gapped wrong and checked them on the net and i have been given the wrong plugs so i put the old ones back in (i numbered them when i took them out so there all back in the same place) but its still got the same problem. Any ideas?

 

anybody?

 

maf sensor on the airbox? diconnect it and see if this changes anything, had the same symtoms with my missus dads mondeo 1.8

 

bit of an obvious one but the leads are on the right way arnt they?

 

i was thinking leads.....i changed the plugs one at a time so i havent got them mixed up....would a knackered lead cause smoke from the exhaust as well as a misfire?
