Hi everyone. I put a nvk5 pcm in my early 99 f350 4x4 cclb larit. As soo. As I touch the gas pedal I get a check engine light and a idm code of p1316 idm codes detected. I have no tuner hooked up right now. And my early 99 XLE4 pcm had no p1316 idm codes.

I did not disconnect my baro sensor under dash. I do t think this will cause it. It's weird because I know others have done this with no issues mentioned. Starts fine with no codes then as soon as rpm comes up the service engine soon light comes on. Any help appreciated as I'd like to run this pcm over my xle4.

I have full force 1.5 180/30 single shots injectors but it's not the cause because I remember this issue when I put it in before when stock. Anyone have any ideas. Is there a pin difference and wiring that needs to be moved I. Pcm Connector.

Thanks for the help.
