Help Me Fix My Car!!
i have no clue whats wrong with it. I just got it back from having my AEM F/IC installed, and am having some issues.
CELs: (cant remember codes, will pull tomorrow)
#1 was low MAF sensor voltage or something along those lines
#2 was regarding the crankshaft sensor
and #3, when i floor the car for a couple seconds, usually in high RPMs, the car makes a sound like its backfiring and loses power during these spurts. Theres no flames coming from the exhaust or anything, but you can hear it happen pretty well and feel the power loss pretty well also
does anyone have any clue at all? AFR's seem fine, however they oscillate quite a bit...even idle is between high 13's t low 16's....i dont know if this is always what happens, or if maybe its a result of my issues, since i got the F/IC installed the same time as the AEM UEGO

possible solutions? atleast to the misfires? my only guess so far is that they tried to start the engine a LOT when they were installing the FIC, so maybe the y fouled the spark plugs? Any other possibilities would be awesome, cause im gonna try and get my superhcrager installed on tuesday, and want all the problems fixed before i do this, since it will probably make any problems i currently have even worse.

the codes are P2432, which is my code from removing SAI, so we'll ignore that one. Then theres the following:
P0102 Mass or volume airflow circuit low input
P0336 Crankshaft position sensor A circuit range / performance
Misfires only occur under WOT in high RPMs, whih is also suggesting to me the plugs are bad, since it would run a lot richer in open loop, causing the plugs to not spark in the denser fuel mixture
Also, my traction control light is on...no clue on that one...

I just looked up the other code and I think you might locate your problems at the pcm connectors .Check the connectors at the pcm and inspect the wiring for any damage.
Might you of hit the connectors during the install?
This is for the 102 code.
Clean the maf and inspest the wiring for damage and that the connections are tight.
Inspect for any contamination or debris on the sensing elements of the MAF sensor.
A wide open throttle (WOT) acceleration from a stop should cause the MAF sensor parameter on the scan tool to increase rapidly. This increase should be from 2-6 g/s at idle to 180 g/s or more at the time of the 2-3 shift. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system.
A high resistance of 15 ohms or more on the ground circuit or the ignition 1 circuit of the MAF sensor may cause this DTC to set. A high resistance will cause a driveability concern before this DTC sets

I haven't attempted much since my last post, but I forgot to include a detail. When I'm flooring it, after several misfires (if that's indeed what they are), my tachometer will drop to 0 RPMs for about 2-3 seconds, and then just go back to normal again. I don't know if this will help diagnose the issue or not, but I thought I'd throw it out there.
