My Seicento 2001 MPI has started to feel like its about to die while ticking over, first it only did it about once a minute but now it does it all the time

Ticking over at only 150-250 RPM which seem to me to be abit low, is it ? Its not cutting out ( never has ) but just feels like it

I have seen a post on here which says something about idle valve, that they do wear out and best place to get one is a scrappies

Just wondered where the tick over screw is ? so i can hopefully sort this out

Thanks

There isn't a tick over screw, its done by the ECU.

Its obviously getting some bum info from somewhere so get it read.

Where is the MAP senor ? And any others that might need checking ?

Thanks

IIRC map sensor on MPI is in the manifold.

When was the car last serviced?

Why not get it read?

Cheers

Easy to change or not ?

Full service done in may

by 'Read' do you mean take to a garage for the ECU to be checked ?

Thanks

Get the sensors checked, not the ECU. An autospark will be able to do it.

Could also be drop in fuel pressure? Or a dud injector caused by dirty fuel?

Saying that, MAP sensor is my first thought. Check that small hose from the inlet manifold to the MAP sensor hasnt perished or come off. Also check that the MAP sensor has a connection to it.

Am going to check the connection when i get back from work 2moz

i always use BP for fuel so i can't see that being a problem ( fingers crossed )

How much is it going to cost me for the senors to be checked ? :bang:

Thanks

I wouldnt know, as i diagnose all my stuff myself the old fashioned way!

Phone some places and ask for a quote would be my first thing to do. At least you know how much you are looking at before you go in.

If its going to be £30, you might as well go get a spare sensor from a scrappy for a couple of quid.

If its a fiver, its worth doing
