Just to confirm, if cold start injector is loose is it a loud shrill sound you get maybe at start up and then as the engine warms immediately after any throttle?

I thought for ages it was a worn alternator bearing but after Peter replaced mine looked closer and the sound seems to be coming from this vicinity

- thought at first it was the hose which connects throttle body

> intercooler intake being loose, but after replacing the cheap jubilee clips present still have the noise.
