coolant temp sensor??????????



  clio 1.4RT
HI all,

To cut a long story short i think my car is over fueling due to black soot on new exhaust and also milage down a bit so im thinking it could be the coolant sensor. oh by the way the clio is an old 98 mk 1 1.4rt.

If i disconect the sensor what result could i expect to see? Will it tell the engine the car is always cold or always hot and if so will it increase fuel or decrease it?

I know i ask alot in this question but all i can think of is either the sensor is buggard or it could be the o2 sensor in the exhaust?

all help appriciated.

p.s if it is the coolant temp seosor what code do i need to buy say from GSF as they have a couple to choose from?
