Blacktop SR20det help needed

[bmar19]

Hey guys. I have been having some issues with my SR lately. I will try to describe everything as clear as possible so I can maybe get a little insight that I'm overlooking at the moment. I have pics and video and you can see kinda what im talking about..and also hear the misfire…

I have a 95 S14 with a S13 blacktop E5 ecu I will list all mods below then go into the issues I'm dealing with as well as everything I have done, tested and tried.

Mods:
S13 blacktop
garrett gt2871r turbo
fmic
wiring specialties pro harness
RS enthalpy tuned ECU
Flex a lite fans for s14 (on all the time)
alternator rebuilt
new battery optima
fuel pump is rewired with a relay and getting 14volts
walbro 255
battery in the rear
denso 550cc injectors
aeremotive FPR
z32 fuel filter
NO BOV
isr intake manifold
new ngk bkr7e .032..used to be at .028 same thing

Ok so issues

when I first start the car it idles up normal for about 10 seconds then rpms drop and sometimes will die and sometimes stumbles bad for a few than can pick up normal then die ... when i start it again its all good no problem.. suspect IACV but cleaned it all out and set idle with TPS unplugged .. It will also almost die when I come to a stop the rpm dip low sometimes bounce around up and down and evens out randomly will die (No bov)

when warm idling
the car will sometimes idle lean according to my afr gauge AEM and the sensor is good and tested... you can hear a slight misfire at idle and the gauge is lean showing 17s to ---

also at times at idle the afr will go to 10.0 and stay there for a few min then something changes and shoots back to lean..you hear the motor miss a beat (misfire i guess) go lean and dies..

if its idling at 10 and i turn ac on it goes lean...turn ac off and it goes rich...also sometimes when ac turns on the rpm don't rise and the car dies...

also at idle...if i turn wiper on the volts drop in the car when the wiper moves and almost kills the car and lets say I hold the rpms around 3k and the wipers move the rpms drop....checked this will a multi meter not sure if this is normal
even just at idle sometimes the car will be steady and randomly the volts drop and car will either die or stumble...

driving...10lbs car will be lean in boost around 13s sometimes high 12s
cruising I'm at 14.5 to 15.1 so normal

my eyes also burn at times when driving…not sure if its just my contacts or what but they do bother me when im driving my car


What I have done/checked:
MAF - 1.05volts at idle. cleaned and tried another no change..its grounded to chase as well
Coils - ohm checked all good, grounded to VC bolt
ignitor - checked and passed
injectors - ohm tested
fuel pump new and rewired with relay
ECU check by martin at enthalpy and all good
engine compression good
no boost leaks
no vac leak (smoke tested)
TPS checked.. .44V and smooth up to 4.7v
timing is correct even tho it does bounce around when checking with a timing light but it was set right


in the pics you can see my grounds i have...i have one off the head to chassis, one off the intake to chassis, one off the alt to chassis, the oem one on the back of head to the bracket, and a ground from tranny to chassis firewall
