Dodgy idle, vacuum leak.

[J@ck]

Car died last week, turns out the coil was shot.. Replaced the coils and plugs, however the car has randomly cut out a few times, plus i can hear an air leak coming from the engine.

Do you think I could have knocked something causing a vacuum leak which is affecting the way the car runs now? Or could something be faulty with the coil/plugs?

Any help would be greatly appreciated!

Vaccum hose on the back of the inlet would be my first thought.

Ph1 of Ph2?

Its a 2003 1.2 clio dynamique, would i need to remove all the plastic upper intake manifold to get to this?

Im going to take the intake manifold off tomorrow and give it a good dig out, hopefull ill find any leaks then as well... Anyone got any other ideas?

replace ALL the gaskets while it's off, even the rocker cover. I've had a vac leak on a 1.2 thorugh the rocker cover before because of the breather system

I've cleaned out the intake manifold and throttle body, there was oil inside the intake and the filter was soaked.. Car seems to be running much better now, however the coolant temp isn't registering anymore.. Possibly could of knocked it..where abouts is the sender on the engine?

Anyone know where I can get a wiring diagram from? There's no signal going to the coolant temp sensor now and it's proving a nightmare to follow the cabling..

get a new loom, they're renowned for corroding internally, wearing through at the ECU plug ends, and generally being crap

Cheers for the advice, after dismantling it all again, the reassembling, it's working again.. Guess I'll just keep an eye on it, hopefully it was a loose connection..
