Hi, Im "new" to this forum so I hope Ive come to the rght place/section! I came here via someone on the bba forum trying to get an answer to something - but didnt want to pay for membership for here!! I have to say, since paying my fee & looking at the archives / discussions etc..it looks to be the best 28 quid Ive "ever" spent! Right ...here we go then.. I hope someone can help.. I have here a Fiesta 1.25 Zetec on an "N" - 1st of the newer shape.. basically its running rough..sort of a misfire but not on any one cylinder..Ive run FCR and come up with Codes 171 and 172 , as you will no doubt know.. this is referring to left bank lean & rich! Im really quite stuck with it so if anyone can help/offer direction Id really appreciate it!! Ive cleaned the MAF and it looks ok anyway.. nothing else looks out of the ordinary either but theres something amiss. Another thing too, it wont idle very well.. cuts out at traffic lights etc. Its recently had a new Idle valve... Thanks for now then Mike
