Q - We have a 1995 ford Mondeo Zetec it runs really rough and keeps cutting out when ever you come to idle, and on acceleration its like its running on kangaroo juice, taken the car to ford twice and they changed the idle air valve, air flow meter and the coolant temp sensor to no avail. I’ve even tried winding up the throttle stop but even this doesn’t stop it stalling aaaarrgh!



Answer -

Relax this is quite a commen problem with mondeo zetec systems, it sounds like you’ve realy driven round the houses trying to find this fault, the problem is probably staring you right in the face all you need to do is listen for it, can you hear a sucking sound around the coil packs I bet you can. This is caused by a little rubber T piece that connects manifold vacume to the EGR system under the coil pack, these little T pieces are always splitting and cause the exact same problem that you’ve just described.
