Coolant Sensor

[johnny406]

I've asked about the problems I've been experiencing.

Poor starting, the car needs to be revved hard before it will idle properly and then be a bit rough until it warms up or switches to LPG.

Poor acceleration until it's warmed up and kangarooing along.

and a Slight misfire on idle (pinging) when finally warm

Been advised to change the coolant sensor, which one should I change and also where do I get one from?

Anything else it could be?

remove multi plug from sensor and check for approx 5volts with multimeter
if voltage is within these limits replace multi-plug back probe plug ign on
if coolant sensor ok you will get a voltage reading of approx 3.4 volts
keep multimeter connected start engine as engine warms up voltage
will drop to approx 1.5 volts if sensor is ok i hope this helps
