Hello group, first off, thanks for the help in advance! Reading over this forum has provided me with a swell of information. I appreciate all you owners and professionals taking your time to contribute! So I just bought this 2007 Fusion SE (3.0L Duratec, Auto, 84k on the O.D.) for $2,400 from a guy who said it needed an engine replacement. It had an extra empty gas tank so, I added one bottle of Lucas fuel system treatment, and a full tank of Premium gas from my trusted gas station. It also had a completely dead battery(Left it on the conditioner and it nursed it back to 94% health). Upon further investigation, it actually drives half way decent. No knocking, doesn't smoke, clean oil, and great oil pressure. While it's running though, the exhaust wreaks of gasoline and it's making this popcorn sound under the plastic intake manifold. It almost sounds like random detonations. It has poor acceleration but once you get going, it'll coast and drive just fine when it has inertia on it's side. It does have a CEL so, I tested that. I ran the CEL and it resulted Loss of PCM/BCM Communication, Cylinder 6 Injector Fault, Bank 1 lean, and Insufficient EGR flow. So I bought the injector and all the gaskets for the intake job, after taking apart the intake, I realized the number 6 injector was actually just slightly unplugged. During the dis-assembly, I payed close attention to the vacuum lines to try to narrow down the Bank 1 Lean code. I found one of the upper intake manifold bolts to be sheared off and a visible leak could be seen (dirt sediments built up over the moisture escaping from the manifold in conjunction with slight oil residue on the face of the intake o-ring). So I reassembled everything, cleared the CEL and restarted the vehicle hoping all the problems would be solved. Unfortunately, the idle is actually more erratic and the popping is much more constant. Upon running the diagnostics VIA the OBD port, the engine only has one pending code for P2198. My interpretation of P2198 is a lack of oxygen sensor switching, indicating a rich condition. So if I'm correct, the fuel system is trying to adjust to an overly lean condition and it's now maxed out on the rich side. So, what I know is that I reassembled and torqued everything correctly and there are no sucking openings. So, what am I missing? I don't see or hear any large vacuum leaks. Any advice would be greatly appreciated. After letting it run, I attempted to hold the RPM's at 2500 to elevate the exhaust gas temperatures. The car can barely sustain 2000 with no level of stability. If you release the accelerator pedal and hit it to the floor, it'll briefly surge to 3500-3800 before bogging way down to a rough and erratic idle. I'm kind of leaning towards a congested catalytic converter due to the fact that there are no other codes and it honestly seems like it just can't breathe. Thank you very much! Video/Sound File Link I have included a link of a video/sound file to allow you to hear the symptoms

I am trying to remove the lock cylinder on my 2007 ford fusion because i have to replace the door, and don't have keys for replacement door, and if i did, i'm pretty sure they wouldn't start my car. I am 16 and really struggling with this one. I have watched countless youtube videos, but no one seems to have made a video for my car. I tried loosening the screw that comes threw the side of the door, and then using the key to pull out the cylinder, but it didn't work. I have to have this done soon so my cousin can drive the car to his national guard training since his car broke. Please help!
