Hi all,

I have a 1997 mk4 fiesta 1.4 zetec-s engine fiesta which is running really rough. Originally the car had breathing problems, was idling at 2/300 rpm, so I changed the idle control valve & that cured that problem, now idling at 1000rpm, but it soinds rough. When you drive it there's not the poke that it normally has, 90bhp whem new, but im not sure whatthe problem could be.

Any advice would be greatly appreciated

    The air filter was replaced not long before I brought the car but I don't believe the fuel filter has been replaced

    Try the fuel filter in any case it's probably due.

    I know this may sound a little silly but where abouts is it located as I googled it & it said the right hand side of the engine bay but I can't see it. I know it's a cylinder with a hose top & bottom but I can't see it in the engine bay

    I'm not sure on a mk4 mine is underneath the fuel tank, perhaps someone else on here would know. Sorry.
