Given that you are getting spurious fault codes (no fuel temp sensor on a
petrol, and definately no shift soloniod on a manual box) and a severe
misfire, i'll bet my lower ball that your coil pack has thrown the towel in
and is spiking the ECU .
Fairly to very common on the 1.6. (though not as common as if it were a
Peugeot / Renault / VAG!)
