Ok so i bought a 92 s13 hatch for 300 bucks, had a blown up motor in it so i pull the motor and tossed it. I managed to find and S14 ka for cheap but upon inspection i found that the valve seals were leaking, so i took the head off properly, dropped it off at the machine shop, have help throw a straight edge on it to make sure it was flat, it checked good, and had them replace the valve seals. After getting it back i went over most the motor and replaced all the seals, front and rear main, intake mani, exhaust mani, head gasket, put in ARP studs, threw it all back together, new clutch, new slave, new clutch master, new brake master, i pretty much replaced everything i thought would go wrong since this is going to be my daily. Before tossing it in i removed all the useless emissions and egr bullshit and blocked everything off correctly. I put the motor back in and right before i started it i had a buddy toss my battery in and hook up the cables while i was messing with my white car, i didn't bother looking but he hook up the cables backwards and it fried my ECU, i got a new ecu tossed it in.
The car started right up smoothly and then immediately ran like 400lbs of shit, if i gave it any gas it would bog and die, if i let it idle it would slowly die, i adjusted the timing with a timing light, same thing. Here is where it gets weird, i unhooked the MAF plug and it started to run smooth and idle a little high and i could even rev it a little but it would still break up a bit until it hit the 3K rev limit with the maf unhooked, so i thought ok, bad MAF right? WRONG! i took that MAF and put it on a buddy's car, his car ran perfect, took his maf put it on my car, ran like dick, no change, so ok, MAF wiring right? WRONG! i put his engine harness on my motor and it ran like aids still. So a couple weeks later he pulled his KA to do an SR swap, so he gave me everything off his motor i replaced the fuel rail with injectors and FPR, replaced the distributor, plugs, wires, fuel filter, used his ECU aswell, replaced the ignitor and coil, replaced the fuel pump and drained the tank and put fresh gas in it, still runs like total asshole i have no fucking clue what to do and it is really pissing me off, i just want to start driving this thing so i can start saving on gas and this is causing more of a headache than anything else
CAN ANYONE HELP ME? PLEASE!
PS!!!!!!!!!!!!!! I also compression tested the motor and got 138 140 140 138
PPSSSS!!!!! just to clarify the motor is an s14 KA and it has everything need to make it work in an s13 and the car i pulled parts from is also a 92 S13
PPPS!!!! The only code I got from the ECU was 55 which is all clear
