That was the crank sensor wasn't it? Running rich is a cracked exhaust manifold, bad o2 sensor, our fuel pressure too high.

The first thing to check is the exhaust manifold by the collector tubes for cracks and the bolts on the manifold especially the ones close to the firewall. Since you have done the mechanic thing I know you have a pressure guage. Check the rail pressure. 31psi idle, 39 psi with the vacuum line to the regulator on the fuel rail disconnected & stays above 20 psi for 20 minutes after key off.
