5 error codes, runs rich, won't idle, but drives fine!

I finally figured out why my new 2.3l stroker engine wasn't running right. The EGR valve blew its gasket and it was a huge vacume leak. And while I did that I changed my plugs and wires. Since my car was a N/T I didn't have a pigtail for the mas so the wires were soldered in place. I happened to find a pigtail so I wired that in while I was at it.

So to clarify, my car was running fine (other then the vacume leak) with no engine light on.

The next day I 1. Wire in the mas pigtail 2. Change plugs and wire 3. I put new gasket on MAS.

I then start my car and it idles like crap and my check engine light comes on and rich black smoke is coming out the tail pipe. I take it for a drive and the car runs great at higher rpms, but if I let my foot off the gas it stalls.

I then decide to check for error codes and I get 5.
Intake temp, MAS, Barometric pressure, TPS and coolant temp sensor. # 25, 21, 14, 13, 14.

Please help!

You sure some of that solder didn't drip onto another wire causing a short? Seems so cause ALL of those sensors run through the same section of the harness.

I put in a different ECU and the car runs fine.

Thanks for the help.
