Hestitation/cutting Out

[charles]

At last I found the cause of the irritating problems I faced the last months :D ;) .

My car hesistated and jumped randomly.

The Ford dealer diagnosted it but could not find anything.

 

Firstly I replaced the MAF that improved the drivebility greatly, but did not cure the problems. Than I suspected the EGR system because when I disconnected the EGR valve hose the problem seemed to go away. But I was wrong, the faults were only less appearent.

 

After careful inspection I discovered corrored wires of the big wire loom just behind the battery. Acid of a previously leaking battery caused solving of isolation, moisture coming from the bulkhead further accelareted this.

 

I ordered a new wire loom (from connector to several sensors, ignition coils and injection), this one costs EUR 144. The replacement took me several hours because some connectors are difficult to access behind the engine. the air intake section have to be removed and the car must be lifted to access it from under the car.

 

The car is now running fine without faults.

 

To my opinion it is stupid to route a massive wire loom just behind the battery. Maybe it is changed in the newer models. I re-engineered the design. I made a rubber protection flap above the new wire loom and connector, protecting it from incoming moisture and acid.
