V8 Vanatage - Fault Code P2106
Discussion
Hi all,
Firstly, apologies if this topic has been raised before. I couldn't find anything related under the search.
Took my '06 V8 Vantage for a drive yesterday. It was immediately apparent there was an issue with lack of power, it didn't sound right, as though not all cylinders were running. Lots of backfiring and limited revs available.
Had the AA to have a look this morning and when they plugged into one of the ECU's, it came up with fault code P2106 - Throttle actuator control system. He cleared the code and when I took it for a quick spin afterwards it seemed to be ok.
Speaking with the AA guy who seemed to know a little bit about the car, it seems as that the most likely cause is because I haven't been able to give it a good run for a little while and been doing short journeys around town lately, the throttle actuator may have become clogged up.
Has anyone else suffered similar issues on theirs, and is it something a good blast will clear out properly now, or should I look to have the valve cleaned out at the garage to make sure it's performing properly and I don't get a repeat? Obviously I'll need to make sure it gets a good run at least once a week too, to stop it clogging again - no complaints there!!
Cheers, Jon

Not sure about the code, but there is a bit of a history on the throttle butterfly.
This is really quite easy to clean - first go to any car parts shop and buy a spray can of carburettor cleaner.
The front hose (the big one on the top/front of the plenum)is held on with a plastic clip - loosen the clip and pull the hose down out of the way.
If you are anal, then open the butterfly flap with your fingers and stuff some paper towel/rag behind the flap to catch excess liquid (DON'T FORGET IT IS THERE!).
Spray the flap and surrounding areas liberally.
You will see the brown deposits from the fuel - these will soften and can be wiped away.
Open the flap with one hand and spray any built-up deposit behind it - wipe up carefully.
Remove the rag/towel from behind the flap.
It is the brown lacquer-like deposit that causes the flap to stick and gives the error code.
The flap is actuated by an electric stepper motor - It is quite strong, but can be defeated if too much deposit builds up - especially if the car does not get taken up to full temperature regularly...
Short runs tend to allow more unburnt fuel to find it's way back to the plenum and gum things up.
