I have a 2007 mustang with a 4.0 V6. The car won’t start. Did some diagnostics and found the crank and cam sensors aren’t sinking to the PCM. Replaced the PCM with one from Flagship Inc. Now the sensors sink up but the car won’t idle. Was able to get it going with the gas peddle fully depressed. Ran like crap and won’t idle. Set O2 codes for running too rich. No other codes were stored. Pulled the plugs out and they were extremely wet with fuel. My mechanic thinks it’s a software issue in the new PCM. The car had new factory plugs and aftermarket wires before replacing the PCM. The car has had the fuel pump replaced as well with a factory part. The car also has not had any modifications to the exhaust system. Any help would be greatly appreciated.
