Title: mk2 digi 8v, struggles to start when cold starts first time when warm???
Post by: Bigdunc on 19 December 2011, 22:17

as title

when car is cold it really does struggle to start sometimes need to open throttle right up to give it a kick, when warm starts first time every time and drives really smoothly even with a highlift :)

could this be the blue temp sender??

or maybe even fuel mixture? as does seam like to much or not enough fuel

Remember to reset the ECU when you've fitted it.

Once the new sensor has been installed, start the engine and disconnect the blue coolant temperature sensor. Rev the engine through 3,000 rpm three times, each time allowing the throttle to close completely. This clears the Digifant ECM fault memory.
