Got a problem wiv my old mans T reg 2.0l Mondeo.
Absolutely fine at tickover, but jerks and seems to missfire under load.It's had new plugs and leads, new air bypass valve and a new air flow meter, but still no different.Funny thing is, it stops doing it if you unplug the air flow meter (hence us fitting a new one) but still the same.
Anyone heard of this before.

 

bttt

 

coil pack? summit to do with fueling maybe, cos if u unplug the air mass sensor it'll give more fuel maybe ? plug gaps?

 

There a small T piece where the breather hoses meet around the back of inlet manfold by the coil back these split and cause an air leak.worth checking and there only about £3.00 from fords.

 

definately no air leak though mate, runs quiet as can be
