C70 ETS light

Have a little problem, hope one of you lovely knowledgeable peope can help.

I have a 2002 2.0 LPT C70.

On sunday the ets light came on and the car limped along very slowly not going over 3000rpm.

I called the breakdown service and they had a look but the diagnostic check showed nothing.

We limped home and were told a few tests to do, the result of which was when the MAF sensor was unplugged the engine picked up and ran normally... for a while before slowing down and making the same chugging sound on idle.

The cruise control still works which is apparently a sign that the ETS unit, which has the original white sticker, is fully operational.
Any ideas would be greatly received and appreciated folks.

Thank you in advance.
