SC400 misfiring.. Codes 13, 14, 24, 31.
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

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.
