Hay I have a KA24DE that will not idle. I got the engine from a friend (he got a sr20) the engine ran strong. After we swaped we had problems to get it running. The ignition good injectors good resistance no check engine light or everything. Car starts but stalls all the time checked the following

ECU Have 2MAF Have 2TEMPERATURE SENSOR NewCOIL GoodSPARKPLUGS NewPLUGS NewROTOR CAP GoodVACCUME No leaksEGR Removed completlyFUEL PUMP New Walbro 255

NO FUEL LEAKSIGNITION GOOD

I JUST GOT IT TIMED NOW IT DON'T STALL BUT IDLE IS VERY IREGULAR AND AROUND 1500-2000RPM

next i will check fuel pressure

Also i need some info on

How to check MAF resistance and what should it beWhats the resistance on Idle Control Valve

I Know it looks complicated but if u have any other suggestions let me know

Do you have a vacuum line going from the bottom of intake manifold to the fuel pressure regulator?

One more thing, did you remove the butterflies inside the manifold itself? It doesn't affect idle iirc. If they are in there, make sure the lever is situated to where the butterflies are open, otherwise you won't have any power above idle lol.
