When starting from cold I have to pump the throttle like crazy to get the car to start, then its still very hesitant for a while untill its got warm. does anyone have any ideas what it could be?
Please help its driving me mad

 

Coolant temp sensor.........

 

Thats what i thought I have changed it for a supposidly good second hand one and its still the same. Guess I need to change it for a new one and hope for the best as It could just be a waste of money if it doesnt do anything, was wondering if it could be anything else I could check first.

What resistance should a good water temp sender have? would be good just to test it that way

 

£40 + vat from a subaru dealer for a new one..

 

Just to confirm you have changed the one that sends the signal to the ecu and not the one for the temp gauge havent you?

 

Yep, think im gonna have to spend some money and hopefully it'll fix it. Knowing my luck though it wont, wish there was a way of testing them to check if the one I have is knackered
