Hi,

I've been given a 1997 Mk4 Fiesta 1.25i to learn to drive in. Apart from being a bit shabby on the outside and the central locking not working, she starts, runs and stops OK. However, there is an intermittent erratic idle: engine revs rise and fall slowly, and after taking the foot off the accelerator there is a slight delay before the revs drop. The previous owner has removed the air box assembly and replaced that with a K&N type air filter, so I'm thinking that could be the cause.

 

I've bought a 2nd hand air cleaner assembly from eBay, and ordered an new filter. Could those who know mind having a look at the pictures attached and let me know if I have the right assembly, if there are any parts missing and what order they are fitted please? A parts diagram would be very helpful if anyone knows if an online version is available. I have a Haynes service manual, but can only find a written description in there. I've worked on motorbikes for many years, and this is my first car.

Thanks in advance,

Hi, it might be idle control valve (could be dirty inside). Often on this fiesta. I have the same car.a0ff8c7fde659dc6cfbc1339a15334ed.jpg
