Engine issue

Not quite..
Modifications are
FMIC, cunningham rods, wiesco pistons, front and rear motor mounts and other related items.
I have the CEL fix on my second o2, but it was damaged recently, so i know my CEL is for that.
I had done a compression test on this motor a bit ago, and it came back at 210 across the board.. im testing again tomorrow.
Anyway.. its just the idle, its rough and missing alot. Coil packs perhaps?

Not to be a Dick, but you are asking a question that with out alot more information no one here is going to be able to help...... First things first, if you have a cel lamp on, i would scan the pcm before i go any further, i know that you have a damaged o2 emulater but dont assume that there may not be any other codes in there..... With so much done to your vehicle this condition can be created by numerous things, vaccum leak, timing off, sensor disconnected or damaged, or various other things.... Hope this leads you in the proper direction...... Good Luck
Fair enough, The motor was already in the car with no issues to date.
Now that the motor was pulled and re-installed, suddenly i have the low idle.
Vacume leak im not counting out, but i spent a good hour scanning the small surface we call an intake manifold. but if it were a vacume leak, wouldn't that create a steady fluctuation in the idle? This seems more random than that, not to mention it wants to, but hasnt stalled out at stop signs..
The cel was poped shortly after the car was started again for the first time, but went away for a day, after i pluged the o2 sensor in..
but during the time the cel was off, the idle was still rough.
I'm fixing the CEl eliminator tomorrow.
I've been over the motor for hours for the last 3 days looking for damaged or un-connected wires.

Not at my personal disposal, i can pay the local garage $75 to scan it, but i wanted to give a few little fix's a go before i went spending funds better saved for parts or even food 
Here in Canada, We don't have a nice place like Autozone to scan our ECU's for free
Though I seriously dident think about the EGR.. I'm more than positive that it's clogged.. Should have removed the damned thing when i had the chance.

IMHO it sounds to me like a vac leak. Do you have a boost gauge ? IF so, whats it reading at Idle? IT should be between 17-21 grams of mercury. If its less then that, you got yourself a vac leak.
