I need some major help.
I have a 2006 Mustang Gt Premium with a 5-speed (188,000 miles) that is not happy. For some context, I bought the car off of a younger kid and it was diagnosed by my dealership that it needed an engine. After further teardown, the camshaft phaser in bank 2 sheared the locking pin on the cam and needed to be replaced. The phaser, cam, cam position sensor and VVT solenoid were all replaced.
The ENTIRE bank 2 section of the engine is cutting out and running great but only off of 4 cylinders. On cold start, it runs perfect, idles perfect and has no issues. As soon as it warms up, or goes under load it completely cuts out.
Lights on:
CEL and enters limp mode intermittently
DTC's:
P0300 - Random Misfire Detected
P0305 through P0308 - Cylinder 5-8 Misfire
P0345 - Camshaft Position Sensor A Circuit (Bank 2)
P0349 - Camshaft Position Sensor A Circuit Intermittent (Bank 2)
P2195 - O2 Sensor Signal Biased/Stuck Lean - Bank 1, Sensor 1
P2197 - O2 Sensor Signal Biased/Stuck Lean - Bank 2, Sensor 1
Replaced:
Camshaft Position Sensor (Bank 2)
Camshaft Phaser and Sprocket (Bank 2)
Camshaft (Bank 2)
VVT Solenoid (Bank 2)
Spark Plugs
Checked/Fixed:
Timing on both banks matched up when valve covers were pulled
Injector pulse w/ noid light (Looked good on every cylinder)
Rewired cam position sensor (bank 2) SIGRN and CPS2 wires all the way to PCM (Resistance measured out of spec through Ford PTS Pinpoint tests)
Removed and stripped electrical tape and checked ENTIRE wiring harness for shorts or abnormality
Borescope showed pistons, cylinder walls and valves normal
122-125 psi static compression on bank 2 (tested with a little bit of oil to test rings and only went up 2-3psi)
180-182 psi static compression on bank 1
I'm not sure what the compression looks like for the 3v's but I'm pretty sure the compression is part of the issue and I could use some pointers for testing and diagnosis.
What I know:
Transmission is fine and shifts fine
Battery/Alternator are good
Timing marks on both cams checked out when pulled and were replaced correctly
Could it be a PCM issue?
