One of mine werent and a bracket was subsequently bent and I'm convinced that's why it ran like a bag of shite

im in agreement with you here. My injector isnt fully seated into the hole. the bracket is bent and there is still some yellow plastic sheath outside the hole that the injector sits in.

(Ive got man Flu so didnt notice this earlier )

anyhoo........this injector 2nd from the right or 3rd injector could be 1 of my problems as my 3rd spark plug is the one saturated in fuel and has the miss fire.

i have a spare injector and line, but when i try to undo it the red injector line turns aswell.........so im kinda not sure what to do.

and having man flu...quite bad.....i can only last a while before im zapped and need a 10 min break.
