correct, to high a voltage back and the ecu kicks up to fast idle by opening the ISCV and leaving it open - been there - done that

its all well and good setting it up for resistance at hte TPS, but its what the ecu actuallt sees back at the connector after its travveled down a scabby old ford loom that counts
