Help please

[DAN HAMMOND]

Hi all, I have recently changed the head on my 182 and since I have done it everytime I start the car it revs up to flat out! I have made sure that all sensors are plugged in etc! Any ideas please? Thanks Dan

Changed the head ?!?

Or the inlet .. The very upper most part with RenaultSport on it ?

You've got an air leak. Take it off and make sure it's on properly when it goes back on.

I have changed the complete head due to cambelt failure, I have had the inlet plenum off to do this! I will double check that this is fitted correctly but I have had it off and on a few times to make sure I have not done something silly, how about throttle position sensor? Thanks Dan

It could be anything.

It's drawing in too much air. That's the only thing that would cause that.

Something is not fitted properly.

I have fitted a 172 head on my 182 block, by any chance are the inlet plenums different?

 

[DannyR]

Yes. Did you change the rocker plate breather too?

 

[DAN HAMMOND]

Yes I replaced the rocker plate breather too, what differences are there between the phase 1 172 inlet plenum to the phase 2? Would all the sensors snd plugs be the same? Thanks Dan

 

[DannyR]

The idle control valve on the back and possibly something else

I had to investigate a similar fault for a mate a while back, turned out the egg shaped gasket between the upper inlet and the breather plate was missing, looks like this

 

[DAN HAMMOND]

Thanks guys, I have replaced the gasket, but I'm guessing the plenum isn't fitting flush to the oil breather plate! Can the idle control valve not be swapped between inlet plenums? Thanks

 

[Ol’ Tarby]

A phase 2 doesn't run an idle control valve

 

[DAN HAMMOND]

Oh right ideal, how about throttle body/throttle position sensor? Thanks Dan

 

[welshname]

That's on the throttle body itself. As it's in the engine bay it comes into the back of the throttle body underneath it.

Hi all I have blanked off the breather on the oil breather plate as pictured below as this is a phase 1 172 breather plate which Ihave fitted to my phase 1 172 head on my 182, can someone tell me where this is suppoed be piped up too on a phase 1 172, many thanks
