United Kingdom, Ford Focus 1.6i, 2001, manual transmission, 39K miles.

Today my engine warning light came on accompanied by a very rough
engine.

The engines attempts to maintain tick over revs, but feels lumpy as if
one or more cylinders are not firing correctly

All the obvious were immediately checked , fuel and all fluid levels
okay etc. Temperature gauge not above normal.

On gentle execration the car hesitates but is derivable - I nursed it
home at 20/25 mph

I have a cheap OBDII reader and this gives the error codes

Fuel and Air Metering
Code 0181 - Fuel Temperature Sensor A Circuit Range/Performance

and

Transmission
Code 0761 - Shift Solenoid C Performance or Stuck Off

I suspect that the transmission warning is bogus (unless someone knows
different) - the car has manual gearbox.

Would a failure of the fuel temperature sensor cause this type of fault?
Does anyone know where it is located?
Is it part of some other sensor/control?
