messsi Posted September 19, 2011 Share Posted September 19, 2011 Hello. I had the engine management light on my display. So I was advised to change coil pack & plugs. Have done this twice now - each time I change them it does solve the problem. But only for about 3 months a time! The light has come back on an this time the engine miss fires as I can hear it in my exhaust an judders when I put my foot down. I have done that self diagnostic an it comes with the code d900. Has anybody got any recommendations on what the real problem is or how I can sort it Car is a focus mk2 2005 1.6 zetec Thanks Johnny!

mintalkin Posted September 19, 2011 Share Posted September 19, 2011 D900 is just a can-bus communication error code,and a lot of things could pull up this code,you need to get a fault code reader on your car and find out the proper fault codes.
