My Ford Galaxy 2.3 GLX is poorly, and I keep getting different advice as to how to cure it, I recently drove 500 miles and it returned 12mpg (it would normally achieve 30mpg on a run like that I did a steady 60 - 65mph on Motorways for 41/2 hours down then a similar speed back apart from traffic. I have done the following: 1: Replaced Maf sensor (twice) 2: Replaced Spark Plugs 3: Replaced Coil Packs 4: Replaced Lambda Probe (Oxygen Sensor) Has anyone any sensible suggestions. The car has otherwise been great I have put 100,000 miles on it in 3 years and until this it has not missed a beat. Peter
