I've been chasing the P2A00 and P2A03 "ghost codes" all around my car for a couple months now (both banks go rich). Its all been a bunch of fun and all but I saw something today that perplexed and disturbed me. I had removed the intake and was digging around looking for vacuum leaks when I discovered that some loon put my #6 coil pack in upside down. The "F" printed on it is clearly inverted and there was a wiring harness bracket piggybacked onto its bolt . A valve cover bolt was also missing, it had angered them I suppose... After yelling and stuff I determined that this character had just went ahead and jabbed a B1 ignition coil from somewhere in there upside down to make it fit on B2.

Now, I'm not a smart man but id like to think this is all wrong, causing dodgy spark and leaking air and what have you. If I were an ECU that would freak me out. I cant find any reference to this sort of thing in the FSM either and don't know if I should let it go or what considering I'm seeing intermittent fuel spikes in both banks not just that one.

 

Upside down would mean the spark it shooting upwards. Twisted and facing the opposite direction is a non-issue, pretty sure a few of them "face" each other stock, in other words they don't all face the same way.

When you say a valve cover bolt is missing, is it one that holds the coilpack in place? If the coilpack is loose, then that could potentially cause some issues. If the valve cover itself is cracked, I could see that causing a vacuum leak as well.

 

This is the one I'm missing right here

 

That's just a bolt to hold the wire loom in place.

 

The P2A codes were resolved btw if anybody was interested. It turns out that nothing was wrong with the fuel system or any of its components. It was the transmission, seems that it gets stuck in 4th intermittently after the car has been held at running temp for a while. It was causing a rich condition during city driving. I've been shifting manually for 200mi now and it hasn't recurred. All the o2 Sensor voltages have calmed down. A/T sucks
