HELP needed guys!!!!

[lochgilp]

im hoping you good folks can help me out?
My car a 2005 sri cdti (150) has been cutting out the last few days it seems to be when i change down into 2nd or 3rd and it wont start again but after you leave the car and lock it and come back in 5mins it starts ok, but today it has happened 3 times so i thought it might be the tuning box that i have been running for over a year(powerclick green) so once i eventually made it home today i removed the tuning box now the stability light and engine lights are on in the dash and is idling at 1500 revs and the accelerater pedel does nothing??????
Any ideas or is there a special way of removing the tuning box

thanks as always in advance

Try disconnecting the battery for about 30 minutes & then try it again

connected the plug on the fuel rail correctly when you removed the box?????

i've noticed a few of these issues popping up where tuning boxes are fitted ! but it always seems to be a problem with the car not the box !

hi dont know about your first problem but when you took the tuning box off you have put the plug back upside down,i did this with mine got the same faults as you.
