Good for you matey!
Ok pal you do that. By the way, it took me 1 minute to find the location of the diagnostic port for your fiesta on google. You couldnt manage it. Thats why I think its a waste of time!! Like I said, your time though. You're dealing with a potentially engine threatening fault. You get it wrong and you're going to cost yourself a lot more than a professional code read. But, you carry on. Good luck to you
I dont like your attitude...
When googling stuff if your excited about things it can easily get over looked, cut him some slack.
