No problem, it will be releated to table {C3907}, if you are running a higher than stock idle (950RPM as an example), the PCM will expect the TPS to be open, not at 0%. You just need to put 0% numbers in up to the RPM the engine idles at.
Without the actual DTC you were getting I am assuming this is the problem, it is quite common.

Cheers,
