It would seem my secondary injection valve is up the creek.

Is there any way of repairing it or will I have to get a new one or will a sprappies suffice?

Insert AA batteries into the rubber couplings by the cam cover, remove the metal pipe work and unplug the airpump....then pretend it was never there....

is that a waaaaaaah ?  :-/

But leave the solenoid plugged in or the ecu will whinge...

ive never understood why it was there in the first place... :-/

To cause the cats to get up to temp quicker, so emissions control can go closed loop quicker...

The AA batteries will eventually corrode and leak so use a piece ot 1/2" metal rod or short piece of 15mm copper pipe with stop end soldered on.

You can remove the metal pipe completely once the rubber couplers are stopped-up, its amazing how much space this creates.

The air injection system was fitted in anticipation of tighter emissions requirements where new cars would have their TOTAL emissions measured from start-up and over a simulated drive, the air injection system stopped unburnt fuel leaving the exhaust and got the catalysts working quicker. I believe a major manufacturer had problems meeting the proposed limits and blocked the introduction.
