Hi all,

My seicento currently has a habit of stalling or almost stalling when warm. When you are slowing down and press the clutch in the revs will drop very quickly and if i am unlucky the car will stall. Usually it will just climb back up to idle revs.

Now this is charatistic of a vacuum leak, or possibly an idle motor fault? However what i want to know is what changes as the car warms with regards to vac lines or the idle motor? As when its cold it operates perfectly, pushing the clutch when slowing down shows the rpms dropping slowly and coming to a stop at idle.

I am inclined to think some part of the idle control changes as the car warms up. But can anyone shed any light on this?

If anyone can help i would appreciate it!

Cheers

Mine used to do this, found it was a vacuum pipe on the back of the throttle body had split, was fine when cold but the heat made it expand just enough to let air in.

same issue Andy was having, was also missing pipes on TB.. there is a nice diagram in the guides as to where all the pipes should go

Quick check of the timing too.

Cheers

Hi,

Thanks for the replies, will check the vac lines tomorrow. The car doesnt have an evap valve anymore so maybe the lines that have been blocked have sprung a leak.

Is the timing info in the haynes manual?

Cheers

Yeah as Blu said, same issue I was having. Had missing pipes on the back of the TB, popped a pipe on there and it ran fine but now its starting to hunt a bit when warm and sat in traffic but that is due to the pipe we put on, splitting
Still need to sort that out..:bang:

crack on Andy, that was weeks ago..

Yeahh i know. Im on cover for work on monday so if they dont call me in and its not raining badly, i will get it sorted then. Maybe even wash the car
And if your lucky, pop down to collect the dash bit haha

Right,

I checked all the vacuum lines and replaced some clips and the car seemed to be better. However driving home at night brought the problem back so i am wondering what effect would a faulty air temperature have?

Cheers
