CAS and MAF Codes

[89_SR20]

Hey guys so I know there are threads on both error codes but its also more then that. So the car died and I took the Sr20det apart trying to find out why only to see it was a ground issue. I put it back together and re-timed it exactly how its supposed to be done. (Used Frsprorts Diagram) and the car runs but rough and when I unplug the MAF it runs in safety mode. But my ECU keeps telling me the Cam Angle Sensor is malfunctioning. Is there any way to 100% comfirm this? It worked fine until I took it for a test drive. Then it threw the code and idles at 700RPM and the dies. Any helpful tips.

(Its a Stock SR20DET Redtop. )I have Spark Fuel and Compression. But the car is running VERY rich. I have run out of options and the local shop here wants 600 to diagnose.

Adding. when the MAF is plugged in the car rev's up to about 2500 then backfires and Dies. Both codes are showing on the ECU Any way to confirm they are the problem?
