Its a ford coilpack, its the "conversion kit" ATspeed sell...

So as an update to my petrol woes.....

This evening has mainly been full of fail..

Started out checking obvious things, power to main relay / ecu (all seems present and correct) ground checks everywhere (as far as i can tell, all perfect), tested wiring from coilpack to ecu, and some other sensors, all seems perfect...Changed the crank sensor, map sensor and temp sensor, all had no change.

Had another small issue in that it idled high, well found the cause to that, had a vacume leak, so i fixed that, only to be presented with the issue of that now it wont idle at all! just bogs out and conks out! Have unplugged ECU for half hour thinking maybe it needed to relearn or something, but to no avail.

So overall this is the ongoing issue...on stock coilpack it starts from cold, and appears to be ok, only very slight missfire..then as it warms up the missfire gets much worse..
With the new coilpack, it missfires fairly constantly, or at least, constantly when you rev the engine / load it...can sometimes hold it at say 2k, and it will sit there smoooth as a kitten firing on all 4, but blip the throttle and it will "Miismissmissmiss" on the throttle up...

Makes no sence to me, only thing im thinking is screwed ECU? Can buy another, but its 150 quid that ill cry if it dosnt fix it! Im deffo remembering why i tune diesels now!!
