Default first gen crv 5spd f20b swap nightmare! help please, running but not good.

Hi guys, problem here with my crv, i did post in CRV/ELEMENT forum, but got one reply, since crv front end is same as 96-00 civic front end, i thought i'd post here as well.

CAR DETAILS:
98 crv 5 speed
98 f20b full lsd swap
Stock internals and stock car
Stock ecu with 3 wire IACV
1 CEL: EGR (but I did the egr delete so I'm not worried and it doesn't come up all time)


REPLACED ON MOTOR:
Timing belt
Ks auto tensioner
Plugs (not wires)
Cap & rotor
Coil (not ignition module)
Tps sensor (not even on motor when I got it)
Map sensor o-ring (map sensor was loose and o-ring wasn't there)
Map sensor swapped (from running normal civic)
PCV breather on valve cover
Various other gaskets

REPLACED ON CAR:
New fuel pump
New fuel filter
New front O2 sensor (Same rear sensor)


TIMING:
I believe timing is right. I didnt lock the balancer shaft and just put the belt on, but timing should be right because I used timing light to check the flywheel and the white (tdc) mark is between the grooves


PROBLEM DESCRIPTION:
I'm at a loss guys,car drives like there is not enough fuel, motor sounds like a subaru when driving. When I first turn on the car it sounds fine, motor is cold and rpms are high (which is good) then I drive up to the first stop sign (car sounding like subaru) and stop completely and rpms drop down to 800-900 motor still cold.... I know that's not right. Plus there is hesitation when I'm accelerating when its cold I feel surging... fuel relay maybe? Injectors? Hard to find replacement injectors for f20b. When its warm, it doesn't surge, but there is still no power/not enough gas. I need help and i'm stuck!


SENSORS/THROTTLE BODY/INTAKE MANIFOLD:
Inplugged o2 sensor incase bad reading (suppose to rich out right?) Drives the same.
Cleaned intake manifold, it was already pretty clean. But I still sprayed it out and wiped it down. cleaned little oil residue on throttle body, not much though. IAT sensor was unplugged and my car did run shittier so I plugged it back in (so its working.. i believe).


WHAT DO YOU THINK?
So, I'm stuck.... few things left to try... let me know what you guys think:
1) Re-time car and leave balancer shaft belt out (I'm cool with the wear and tear and extra vibrations)
2) fuel relay has not been touched, maybe swap out with a civic? My buddy had one, should I even try? Right now car starts up every time without long cranking.
