Any advice or guidance would be greatly appreciated. I have a 2008 MCS that I bought in October. Love the car but it’s been one problem after another. Last major work i had was the timing chain done back in February. I’ve had the code, P2096 Post Catalyst Fuel Trim System Too Lean Bank 1, since I’ve had the car and pretty sure it’s because I’m getting no voltage from that O2 sensor even after swapping it out. I’m currently ordering a Bentley manual to attemp to trace the wire to make sure it’s good but with that being said, the cars been running fine up until last weekend. I lost power on the highway and managed to get home to start troubleshooting it. Ran the codes and came up with cylinders 2,3,&4 misfires. Troubleshot it further to cylinder 2 (I’d pull up on each coil while running and observe the engine stutter) I’m getting spark at all the coils and replaced all the spark plugs but continue have an issue with cylinder 2, I get no added effect from cylinder 2 when I pull up on the coil. I have swapped the coil positions to see if the problem follows but it stays. I will also add that the spark plug had a good amount of build up on when I swapped them. Any ideas what to do next??
