Help O Wizadrs Of The Honda!

I recently built a B18C1 up for a buddy and it ran awsome for 2 months now but last night this thing went haywire. Symptoms: IAB, AIR TEMP SENSOR, TPS CODES and it will only rev to 2500 and sounds like it's bouncing the rev limiter. Compression is up over 240 in all holes, injectors are all hitting, spark is there, and all conections are good.
Would one bad sensor cause all three codes to flash??

I tried a extra p72 I had and still did the same thing. Sometimes it will run fine after reseting the ecu but only for short period of time.

Any help would be appreciated! THANKS!

make sure all the sensors are connected to the right spots and connected correctly, and if you have any extra ones, see if they work. Sounds like a sensor is messed

Have you done any recent work to it and got any of the sensor wiring flipped around? Honda kinda fucked up when they did their wiring and made to many of the sensors have the same plugs. You can get the IAC and the intake temp sensor flipped around, as well as the MAP and the TPS. Most cases if you get the IAC and the intake temp sensor flipped its gonna fry the temp sensor. That's where i'd look first.
