General Cinq is being strange

[Nick7214]

Afternoon all

I have not been on here for a little while due to selling the sporting, but now have a SX that i have been driving for a few weeks, but it has started to play up a little.

The problem that i am having is it over revving at idle, if i remove the vacuum pipe from the valve locationed next to the where the ECU is and block the pipe up, it then seems to run ok.

So i bought a new valve unit and replaced it, plugged the pipe back on and it is still doing the same.

Just for clarity, this vacuum pipe comes from teh front of the carbarutor and runs to a small black plastic units which sits by the side of the ECU.

What could be the problem with my car.

Please help

Sorry for my spelling and grammer but am trying to write this before my boss notices

Is the pipe itself OK? I take it you mean the map sensor?

The pipe seems ok,

It has a rubber elbow on it and then a plastic pipe to another elbow which then connects to the black box.

It could be the map sensor but i do not know.

If it's bolted to the ECU bracket on it's own bracket then yes that's the map sensor.

To me it sounds like the pipe is leaking.

Take the end off the map sensor and put your finger over that. If the car then idles correctly its the map sensor, if its doesn't, its the pipe or connectors.

Thank you for all your help,

I have now resolved the problem and yes it was the pipe.

I also amended the tick over and now the car is running like a dream

Thank you again
