Okay, i think i've found out why my idle is so screwed up, i took a light today and shined it under the upper intake and can see one of the primary injectors.

I sprayed brake clean on the base of the injector and the idle droped big time, but why wouldn't it be leaking fuel??? Maybe suction the of engine.....

Anyways, i just put a new primary fuel rail on about a 2 months ago. I put bran new o-rings on the injectors but I forgot to lube the o-rings when i installed them. Is this why they are leaking from not being lubed???

fuel doesn't leak from the seal on the bottom of the injector, there is no fuel or fuel pressure there. all the fuel is in the rail and the injector and it can only leak at the top of the injector.
yes you are suppose to lube the o rings but if you are not leaking fuel, your small o rings are ok. you need to replace the lower grommets
i hope this made sense
