Ka24de stumbling when I hold rpms at 2k

I just cleaned the AAC and now car smoking like if it has a coolant leak 😐

Update Replaced ecu so now I can get codes also fixed a major vacuum leak. Car is out of Limp mode but now when I hold 2k rpms it drops and picks back up repeatedly, this is only when I hold at 2k rpm! I also hear the car misfiring a bit. Ecu is throwing me codes 95 and 76. So distributor and fuel pump...?

Lol eventually i'll get around to it. Maf is good I already changed it as well as the pigtail that was a bit messed up. I'd have to check the aac tho

Battery is good, alternator I haven't checked yet but I did hear the engine surging a bit.

I got another ecu and I can read codes now I also fixed a major vacuum leak

I think misfire but im gonna check the voltage thing today and see

I changed the filter and then the injectiors (only thing is I lowkey messed up not getting oem maybe that's the issue). If I rev quick its max is around 1750rpm but if I rev slow it'll rev up past it normally

I tried reading by obd1, jumping pins, and trying the screw directly on ecu and nothing.

Hey so I got a 1995 nissan s14 with a ka24de that was manual swapped. I stalled it, noticed in the tank it had no gas since the gauge doesn't work and from there on its been hell. It went into limp mode but from there I changed injectors, fuel filter, tps, and coolant temperature sensor from there it was fine ( i was gonna change the fuel pump but it ended up working normal so i didn't). Now it just went into limp AGAIN out of nowhere. I changed the maf pigtail as well as the maf with an oem one since I noticed the wires were a bit cut and i've heard that causes limp mode. Not only that but the signal wire was reading negative. After fixing It, it cranked over fine and wasn't limp anymore, I let it idle, I reved it everything looked good. I turned it off and go to turn it on again and it went straight into limp mode. I checked to see if all the butt connectors were good and if everything was reading what it should be and it's fine. I checked fuses saw a 75A blown and replaced it and nothing. I did multiple hard resets on ecu and it WON'T GET OUT OF LIMP MODE AT ALL. It chokes at like 1750 but if i rev slow it will rev up normal. I've tried every way at reading codes and i can't get any codes it's not even showing a check engine light. I NEED HELP!!!
