Inspired by your efforts Phil and also because of a pong of petrol from the air intake trunking while changing the air filter the other day and a few other things that on their own would be "just one of those things" but together all point to dodgy injectors, i bought a set of Omega 3.2 V6 injectors on ebay today.
Not reconditioned/new like yours but apparently in excellent condition and a nice price as well.
Will add to this thread with my experiences when i fit them.
