G'day all - my 95 v8 snuffed out above idle the other day (fairly hot and humid conditions - 35 degrees celc). Had all sorts of dramas re-starting and it smelled like it was over fueling. Got it started by holding foot to floor and cranking - cleared and would rev cleanly over about 2 grand, but below that would die of quickly and stop. Felt like it was flooded. From 2 grand to 5 grand it runs like silk but has huge dramas below that and starting hot. I started it dead cold this AM when afer a cold night (it was outside) and it started well - that all makes me think that the coolant temp sensor has gone out to lunch and the computer has defaulted to a rich setting for start up and idle, which is causing the flooding. Any comments? | ||

Could be but sounds like ignition amplifier - cuts out at high temps. Works when cool. See www.rangerovers.net in the Classic section. Info on temp sensor and ignition amplifier. | ||

Fuel temp sensor not the coolant sensor. Fuel temp sensors prime function is to stop it flooding when the engine is hot. | ||

Its got a new amplifier - Australian Bosch. | ||

Scott both temp sensors are easy to test,all you need is a multimeter some hot water and a thermometer. 20degc = 2.5k ohm 40 = 1.2k ohm 60 = 600 ohm 80 = 350 ohm 100 = 170 ohm Give or take a bit. Flooding on hot start up is generally the fuel temp sensor. fuel temp sensor also helps control the thermo fans on the rad. The ecu uses the fuel temp as a measure of under bonnet temp not engine temp. While engine temp should remain pretty constant (all things being equal) under bonnet temp changes with the temp of the day. | ||
