I took battery off mine once and it came up code and then turned off and on again and it was going fine. Dont know what went on to do that thou, I dont know my code.

Pretty sure these things don't use codes but the radio instead talks to the bcm for security so disconnecting the battery will cause the radio to go into a sort of code mode for a couple of seconds

Hey gasman, make sure the solenoid is connected like so.

If it already is connected this way make sure you get it checked on a dyno.

PS: I apologise about the diagram

Sorry to be pedantic but my bottom hose connects to the side of the solenoid, not the very end. That's correct isn't it?

Read through this whole thread this arvo lol. Umm'd & ahh'd about doing this (I've only had the car since Saturday), but in the end I decided to go for it & give the solenoid a hit of WD40. I'm really impressed with the increase in responsiveness down low. (is responsiveness a word? :dontknow: )

I also came across this about cleaning the throttle body:

yea the throttle body clean works a treat easy to do as well I was scared at first but easy

sorry that its AFF but here http://www.fordforums.com.au/showthread.php?t=73561

includes info on Throttle Body cleaning and boost solenoid , and Torquing of exuast manifold bolts

Is the aim of cleaning the throttle body just to allow the butterfly to move more freely? ie: so it's not all gummed up? Is there any reason you'd clean deeper into the manifold? Would this have any benefits?

Not sure on the TB reasoning, but I think it gives smoother idle. But anyway, I stick my fingers in as far at they will go :blush:

Helped a lot with my rough idle problem, though it's still there so there must be a deeper cause. Hadn't cleaned mine since getting my mods put on 35,000km ago, time flies! Was filthy.
