Ah, yes, just had a read..

If it's still limiting, the cam sensor could be a suspect, but I have never seen one fail on a V6 before...

Code 19 never lies.. I wonder if the new one is duff? you didn't route it near the exhaust did you, hence damaging the cable? ( I have to ask! )

What you really need to do, is clear the codes out with Tech2, and then see what returns.

If you are not getting an EML at all, and it's rev restricting, don't rule out a blocked exhaust/cat

shove a rubber glove over the tailpipe, see how fast it inflates it!

The ECU is not happy with the crank sensor.

The fitting of the sensor, was the orignal route followed, or the alternative route to ABS?

Alternative route for cable to avoid exhaust

Not limiting at all just this stalling at idle after engine is hot

So to clarify, the car is revving up to the redline now OK?

Usually, stalling like that, if not crank sensor, I would say check the ICV and EGR

But I'm not convinced, you have a code 19..

I think the next step, may be a continuity test between the crank sensor cable attatchment (on the loom) back to the ECU pins.

Check out the resistence, and any short to 0v..

You'll need a wiring diagram/TIS

Hang on a mo.

If you have no EML but when you read the fault codes you get a 19 it could possibly be the old fault code.

The 19 code must be stored when the ECU sees a transient fault but isn't cleared immediately otherwise you would'nt necessarily see it.

Not sure how long this code persists but some need 20+ full clean engine starts to 'fade away'.

That's detailed above...

Wouldn't explain the stalling though, which is a classic crank sensor symptom

Still suspect a wiring (or cable routing) fault...

Yes indeed it is revving to redline and driving well it has stalled once since change after a 45 mile run on motorway.

Fault code still reading 19

That 19 really isn't good. That should have disappeared by now.
