Ka24de running like poop

[turbo please]

Ok so my 240 is running like poop. It's a ka24de and so far I've replaced the plugs wires cap rotor coil pack and coolant temp sensor. Timing is to spec at 20btdc, checked with a timing light. All plugs are still coming out all black. And all injectors are reading around 13 ohms. The ECU is throwing a code 12(MAF) but this is my 3rd MAF if tried. Idk what's going on with the car please help.!!!

Could be a fuel injector leaking. That could be causing it to run rich. Disconnect each injector wire one by one to see which one is it. Also check for vacuum leaks they also cause a car to run like crap.

Check your MAF...

What you should do is familiarize yourself with what the trouble code entails.
After three count them 3 mafs, you still get the same code and have the same symptoms. because (you cleared codes and replaced the plugs). <--only slightly important!
Someone whom is the definition of insane would replace something 3 times and expect a different result, so if you are I'm sorry!
What you should be looking into is wiring for the mafs or the ecu, now don't bother trying another mafs. Unless you where using, mafs from other years and or makes.

I've unplugged the injectors one at a time and the motor will miss on that cylinder like expected. The MAFs were all 91-94. And for some reason the ecu won't clear the code. Ive tried both ways with the screw and the turning the car on then off way. Is there something I'm doing wrong to reset it?

To reset the ecu disconnect the battery and press the brake pedal for 30 seconds. Then plug it back in.
