Well gentlemen, I have found the error of my ways, it is lack of attention to detail.
I Had a 2001 Explorer Sport with 106,000 miles that was not well cared for as it was previously a leased vehicle, owned by some ****** smoker ----- cough...cough.
As a result of not keeping up with fluid servicing, the oil viscosity was frequently low and the primary chain tensioners were not doing their jobs as they were under-engineered to begin with. As you would expect, the driver's side cam chain was slack and slapping the krap out of its guide until the nylon was obliterated and the chain was on metal.
The misfire codes leading up to this problem were probably due to cam timing, and the myriad of problems that result such as cam position sensor misalignment, valve timing events too early or late, noise being picked up by a knock sensor if the vehicle even has one.
Well, I purchased the OTC cam timing kit, and a cheap offshore manufactured timing chan set which was suprisingly compreshensive although questionable on longevity. All in all I spent about 600 bucks with the felpro gaskets that I purchased for the timing cover, valve covers, intake manifolds, and oil pans. That covered tool kit, gaskets, and timing set.
It was not an easy job pulling the motor, but not the first sohc engine swap I have done. Since I am now adept at this valvetrain service, I should concentrate on making some money with it.
Anyway, when the engine started up with misfire, and rich/lean codes, I was quite dismayed, and rather frustrated. I know it is a lot of suspense listening to all of my bullshit but it is worth to find out where I went wrong in the re-assembly.
I did not think from the start that I had cam timing issues, like I said, it ran like a raped ape at WOT so it was doubtful I had serious issues with cam timing. The problem was theO2 sensor connectors for B1S1 and B2S2. They were backwards. I had the B1S1 connector on the driver's side. I was switching back and forth the connectors for B2S1 and B1S2 on the passenger side. Imagine the confusion of a closed loop system feeding fuel to the wrong bank --X-- and getting input from the wrong bank.
Oops.
Oh well, next time the system is not idiot proof, I will connect one sensor connector at at time and read the scanner to determine if it is the correct location for that O2 sensor. Since the front two O2 sensors on my vehicle have been changed out to a generic sensor with no matching alignment tabs for each connector it was not idiot proof. The entire harness that is connected to the sensors was by itself on my garage floor at one point. It is much easire for Ford to install the harness on the engine/trans without the body on the frame, but not so easy to reinstall the harness during an engins swap. I will know better next time. Last time was easier.
Thanks very much for eneryone's input, it was appreciated even though I was an ####### at times. I will endovour to do better, and perhaps give back some technical experience to this site eventually.
