Have you got any diagrams of the jets that maybe blocked? ??
I suspect the recirculating air flap isn't moving, common fault.
Can you just clean it up with contact cleaner?
How much are the sensors
Lets break this down one by one..
A couple of things from what has been mentioned on here so far.
When you cleaned your MAF was there oil on it dripping, or was it just a bit dirty but dry? If it was dry then you shouldn't have blocked breather nozzels on the inlet manfold so you can rule out having to do this job.
The SC should engage at about 1300 rpm. With the engine off look down on the left side of the engine and you will see the outer edge of the SC clutch wheel. Put some white paint or tip-ex so that you can identify easily when the engine is on and to see if it spins. Now with the engine rev the engine from the throttle cable on the right and if it engages it will start spinning at about 1300 rpm then off at idle.
IF it dosesn't spin then lets check the butterfly dump valve on your airbox. Undo the top jubilee clip and move rubber tube to the side, rev the engine and see if the flap moves. It will close when the revs reach 1300rpm and open at idle. This is what gives you the boost as the SC compressed air is forced back into the engine, then expelled when the flap is open just like a dump valve. If the flap is not functioning I would first suspect the MAF is faulty, as this directly links to the SC via the ECU and would rule this part out before continuing. You can try disconnecting the MAF but best to try and use a friends one and just plug it in to see. Do this first before moving on.
IF the MAF is good then go with what others have suggested, I bought a new air flap on ebay cheaply as mine blew along with a MOSFET inside my ECU when I floored it one day and blew an ignition coil ! I manged to fix my issue which was the SC always being on, rather then what you have is with not engaging at all. Fixed with the help of the forum and a steady hand with soldering !
