hi there
okay ive had my wagon for three years and has allways had this prob,
its got a bad flat spot when u put your foot down when cold allmost dies very scary trying to get onto the highway. doesnt idle very smooth and bad fuel economy, the coolant light on accasion comes on levels are allways fine.
my local ford place witch i purchased from has replaced coil pack, injectors, leeds, plugs, fuel filter (fare few times). same thing every time i go in and nothing seems to work only my card going through the eftpos machine, have given up but fuel prices and bad economy pissing me off.
any ideas????
cheers

Maybe the coolant temp sensor is stuffed - Now, before anyone says 'it would have set a code' it will not set a code if the sensor or its wiring cause the signal getting to the ecu to be out a bit but not 'out of range'. For example, the ecu maybe thinking the engine is very cold, so it runs rich! : but it still changes a bit in output as the motor warms up. Remember too, you may not always see black smoke for rich running. So, I would change the coolant temp sensor (cheap and easy to do yourself) and check all of its related wiring. Also, does the car have the correct and (working) thermostat?
