I just installed my frankencar intake, i followed all the directions including the reset the ecu and take a ride. Now, my service engine soon light is on. I put the ecu in diagnostics mode and read the codes then looked them up. i got a few codes about the throttle position, 1 about the mass airflow sensor, ect. I cleared it and everytime i clear the ecu i keep getting different codes. Did this happen to anyone else? How can i fix this. I tested the mass airflow sensor, I tested the throttle position switch, ect. Any ideas?

Im pretty competant when it comes to doing things to my car, and willing to do anything to get rid of that engine light short of going to the dealer and getting charged an arm and a leg to fix something simple.
