Finally got the bearings changed in my monster (97/98 ram 1500/2500 360, 5speed 4X4) and and set it up with hemifevers 91 octane tune. Now it keeps giving me a P0000 code, and the reader (SCT X3) doesn't know what it is.

Any ideas? Truck still runs great, for what it is. Just trying to find out what this code is.

 

Apparently that's the code the PCM gives when it thinks something is wrong, but, doesn't know what it is. Are you getting any symptoms? Any other codes? May want to email Sean, and see if he can shed any lite on it.

 

Thanks for the reply. Only change I notice when it comes on is it seems to go from slightly lean to slightly rich, or maybe the other way around. Less exhaust popping on decel with CEL on. I get ahold of him and see what he says.
