Could I have some advice?

I am going to clean the throttle body on my 2003 fiesta 1.4 petrol and it seems to be a good idea to change the gasket. I didn't want to take it off without having the new gasket so don't know what it looks like.

I have seen a drawing that shows a o-ring seal as it does here:

And also a silicon gasket that looks similar like this:

Do both need to be changed?

Thanks

Its always advisable and good practice to re-fit components using quality new gaskets.

Thanks.

Got round to doing this the other day.

The large silicon gasket seems to be for ST. My fiesta needed the o-ring gasket but didn't need changing as it was in good shape.

The throttle was really caked with 90,000 miles of varnish/dirt and I used half a bottle of throttle cleaner on it! Can't believe the difference it made anyone who has not done this really should.

Obd diagnostics said before clean throttle at idle was 13% open. Now its at 2%. So much better idle, and amazing performance difference too!
