Ford Falcon 2001: Surging when cold

...

My 2001 AUII Falcon XR6 has developed a surging problem when it's cold in the mornings. When you accelerate through the gears it's initially unresponsive, but then surges forward like it's trying to catch up. It happens two or three times after starting from cold and while letting it warm up reduces it it's still there. It is not a problem once the car is warmed up. Any ideas as to what could be causing the surging when the car is cold?

The sort of surging you talk about suggests it isn’t getting the cold enrichment it needs to run smoothly during that first phase of driving. It’s probably that the computer is not being told by a sensor to deliver more fuel to the engine, so check the sensors on the engine, and you could check for a faulty connection in the wiring loom.
