Just swapped out the plug wires w/Motorcraft set at 130k and now have a CEL w/ the following codes:P0106 Manifold Absolute Pressure/Barometric Pressure Circuit Range/PerformanceP0401 Exhaust Gas Recirculation Flow Insufficient Detected

Just a coincidence or did I knock something loose while installing the wires? I'm not seeing any obvious cracked/disconnected hoses or loose connectors at this point.
Any suggestions?

Thanks!

You had to have knocked something loose, wire harnesses or broke some wires...
A plug wire change would not cause that.

This is the EGR w/MAP Sensor:

Check the harness and hoses.

I think someone said the EGR and MAP are one unit...

Thanks. I'm not seeing anything obvious, and although changing out the plug wires was a hassle, there wasn't any serious yanking and tugging involved.
I'll get a hold of Tasca and order an EGR unit. I was just concerned because there are a few posts where replacing the EGR unit didn't cure the CEL popping up.
