squirt gas everywhere?
Wiggling the injector shouldnt affect fuel flow and prolly wont move

look closer and wiggle softer at the harness and connection.
Just sayin' check the obvious first... if moving the actual connector
affects then it's either in that connector or the injector pins/winding

OK, tried this - no difference. I'll probably get to removing it Monday
