My car has 95,000 on the clock, has just started getting stuck in Drive and losing power. Drives fine for days, then halfway through a journey just seems to get stuck and lose power, you can manualy drop down the gears but still wont go faster that 70/80 mph after a slow build up to that speed.
any help would be gratefuly recieved, thanks.

Air mass Sensor, split turbo pipe, could be other things but the 1st is the most likely.
You need to get the fault codes read.

Don't forget to check the air filter too. A blocked one will cause lack of power.
