Hey Folks,

This is my first.... probably of many posts here - so Hi All!

About a month ago, the Fiesta (1998 1.25 Zetec) failed it's MOT on emissions, however I've spent quite a bit on it over the last year, so even though it's not worth thousands, I don't want to scrap it, plus apart from the engine, it passed with flying colours!

So, I have four options:

1) Fix it - wouldn't say I'm a full blown mechanic, but could get through it with a few swears and screams!

2) Buy a new engine - I'm in Leeds, found one in Manchester at 175 all in, but don't know the mileage, then fit it.

3) Buy another Fiesta with 12 months MOT, pull the engine out of it, throw it in mine, get it through it's MOT, then change the engines back... cough cough - obviously this is hypothetical!

4) Get the engine rebuilt - but it's 500 and really don't want to spend that much!

Anybody hit this problem before? I've heard it's quite common and a lot of them give up at 60k.... guess what, mine's done 60k!

Any help would be amazing - anyone gives me a quick fix, I'll get them a pint....... but you have to come to Leeds!

Cheers,

Richard.

you could clean the lambda sensor and make sure its not covered in gunk, if you only do short trips the engine could be choked up try taking it for an 'italian tune up' to clean it out

Most emmision failures are due to the lambda sensor so i would try that first

Have you tried putting some "cleaner" into the fuel and giving it a long run before your MOT.
I just had a service on mine by a ford dealer who put some Halvoline cleaner into the fuel that supposedly lasts 6 months. The Lambda sensor as already stated is another prime suspect, my sons last peugeot failed its emissions, after a week of replacing bits with no luck it turned out to be the lambda sensor! They only last a few years and once clogged up fail
