Check engine light came on. Diagnosed with bad throttle sensor and EGR module. Both replaced. Drove it home, check engine light came on again. Returned to shop, replaced the computer. Left again, light back on. Saying a short between computer and the sensor and module. Can't find it, any suggestions where to look? Or is it something else?

As far as sensor issues, I check the wiring circuits first, ref voltage-- ground--signal, where applicable, go from there.

If you know which wire has a short, leave a pigtail at both ends, splice in a new wire. Sometimes the connector has a problem?
