chasing down intake leak
 

I've been getting radical a/f readouts under partial throttle, but seems o.k. under full throttle. When I sprayed the top of #2 injector the idle dropped then came back up. I wanted to check #1 & 3, so to get access I removed the turbo boot between the turbo and intake. Now the motor won't start. Does that boot need to be in place, or is something else going on?
