Technical cold starting/ fuel economy

[BLONDEBLOKE]

My 1.4s brava used to be fine (36mpg!) now its got cold start problems - have to start it on the throttle until it warms up otherwise it stalls and the mpg is down to 30. Before i change the injector/ air temp sensor etc, anyone got any ideas or had a smilar problem?

Hi,
resistence for the temp sensor should be 2000- 2500 at 20°, 1000-1200 at 40°, 300-330 at 80°, so check this first before moving further.
