Fuel injector issues
A couple of weeks ago, I wrote on here that I was having problems when I started my 95 3.0 4runner. It would idle for a while and then push one of the injectors out of the fuel rail. No clue why
I did everything from dropping the fuel tank and having it hot tanked, blowing out the fuel lines with compressed air getting all new injector seats and o-rings and a new fuel filter. Everything installed per FSM. Started it up and immediatly 2 injectors were pushed out. SOOOOOO.
I opened the motor up again and placed an extra rubber grommet/spacer between each injector and it's seat so that the injector has no room to be pushed out. I ran the runner for about 45 min without any similar problems. Question is, will this cause me problems in the future. The injector spray holes still extend past the grommets, but there is not 1/2" of available up/down space for the injector to move. Any thoughts are appreciated.

This may be hard to describe, but I think you are missing the bottom spacer for the injectors.
Should stack like this, top to bottom:
fuel rail
injector O-ring (on injector)
rubber grommet
injector
rubber o-ring (on injector)
spacer (MISSING??)
o-ring (MISSING??)
