1JZ/240sx

Well, I was recently driving my car and all of a sudden the engine started to missfire and run as if half of the cylnders died.


So I did the self diagnostics and thiese are the codes i received.
13- RPM Signal Curcuit
14- Igniter Signal
24- Intake temp sensor curcuit
31- Low air flow meter voltage

FYI: plugs, plug wires, distributor cap & rotors had been replaced prior to this problem.
So i borrowed a friends MAF, bought 2 new ignition coils and replaced them, but still not firing.
tried resetting ecu to see if i got any different codes or difference in idle.
No luck.

Is there anything that I may have overlooked, or misunderstood from the codes?
Thanks in advance for any insght

If it happened right after you did the maintenance items, try rechecking your installation. Double check all the connections especially the distributor wires, cap, rotor...

no but
it happened immediatly after installing a new a/c compressor.
The car idled fine while the compressor charged. for roughly 30 min. I did not test drive it that nite.
The next day got in and drove about 1 mile and the power died
not sure what that could do, but you never know..

I also only swapped out the MAF sensor. i did not swap the whole housing

all of the above maint was done at least 600 miles ago.

You have to disconnect some hoses/plugs to get to the ac compressor correct? Double check all of those connections. Seems like a loose connection to me.
