inlet manifold valve 1 blocked

[torquey]

As title c20let code where and what is it how do i go about fixing it.

[Rob H]

Not much info about that particular code is there, if it was me id start by removing the inlet mani and having a good look about see if anything looks suspect, checking all vacuum hoses etc for blockages if you haven't already. Quite often with these sort of things it's quite obvious when it's all apart.

[torquey]

No its annoying got me racking my brain believe me. Ive checked inlet and all vac lines carnt see anything wrong.

[Rob H]

Bit of a long shot but maybe try phoning or popping into a dealership or 2 see if anyone would be willing to explain what the code is. Surely the official vaux code readers or whatever they use will have some sort of info on it. Maybe lead on that you want them to fix it but need to know what it is so you can get a guide price or something lol.

[torquey]

Yeh will try that can only see. Its a strange one as there aint much info on the code. Cheers for your help.

I wouldn't pay too much attention to it - sounds like one of those silly ambiguous codes you sometimes get... I know that the inlet doesn't have it's own valve! lol

What are the symptoms?

[torquey]

Right symptoms are bad idle from cold missing a bit until warm. Holding back on boost.

Ive checked the following
cts new.
wiring
vac leaks
injectors out and checked
plugs
.

Have you got a spare AFM? Exact same symptoms I had a few years back

[torquey]

No need to swap it over and see.

[meritlover]

Disconnect the MAF and see if its much different.

[torquey]

If i disconnect the afm it cuts the engine.

[Will F]

Have you got another one to try though? That doesn't really mean anything if it stalls the engine...

[torquey]

No carnt find one at the minute!
