1998 ford ranger 3.0 farm truck, high idle, not a conventional fix, but if it works...

Smoke tested with smoke machine and found no vacuum leaks, I lost the footage of that. Engine still pulling to much air with throttle body completely closed. Changed pcv valve with no change. I slapped in a Used Computer with no change. Engine was swapped from something else that I do not know the make or model and if their was a difference in throttle body's from different years. So this is the repair I decided to make and so far it seems to be working ok. It could be a MAF or TP Sensor contributing to the issue also, but I didn't want to spend hundreds of dollars on parts swapping sensors on an old farm truck, because they do seem to be working according to the scan tool.
