vacuum/boost/fuel/injector question

ok... when reassembling my motor, we re-used the upper injector o-rings and DIDN'T EVEN PUT lower o-rings on (the picture didn't show any, I assumed that meant there weren't any! stupid me )

So, anways, this is going to cause a boost/vacuum leak, right?

How bad could it possibly be? Could this solve my lack of boost problem? And my milage? and my stupid bouncy idle? and... etc, etc, etc?


Since I'm ripping off the UIM, is there anything else I should be replacing while I'm down there, that I probably didn't look at the first time?

Grommets are grommets and o'rings are o'rings. There is but one o'ring per injector. There are two grommets per injector. One on top...one on bottom. No o'ring on the bottom.....be lucky if it even starts much less run evenly.

it has been running, really great. But my idle pulses(annoying as hell) , I seem to have a lack of power (tops out at like 100MPH) and a lack of boost (stock boost gauge tho, so who knows how much I'm really seeing... )
and REALLY awful fuel consumption, like 12-14MPG.

I've got used o-rings on the upper (secondary?) injectors but NO o-rings on the lower injectors.. they're wiggling around loose.

Running really great except for the pulsing idle, lack of power, lack of boost and high fuel consumption?

You'll have huge vac leaks. Take the injectors out and install new o-rings.

Thanks!

well, like, when cruising, or whatever, it runs well, smooth, no misses, etc... But when at WOT or idle, thats when the issues appear.
