OK, so, the car seemed to drive pretty well for a while after they replaced the CMP sensor. Drove it for about 15 miles, stop and go and some highway. Had some mild hiccups, but not bad. So, I shut it off and turned it back on and the MIL came back with a code P0340 (Cam sensor malfuction).
I googled around a bit and found a couple of things regarding this. One described my problems exactly and said to run the vehicle with the alternator disconnected. I did that, still no fix. Also, Justanold helped me with getting my speedometer issue squared away and then the CEL came on after that, so I even tried it with fuse 35 pulled just to see if things were related and they are not. So, now, here I am trying to figure out what kinds of things can cause this problem. My obvious choices are:
1) Plugs and wires replace
2) Take to Ford to reprogram/update the PCM (There's a TSB out there regarding my vehicle, from what I can tell)
3) Take to Ford and have them diag it (which requires a fair amount of bending over, if you get my drift).
Anyone encounter anything like this before? I've seen tons of posts regarding this code and I have seen people replace plugs, wires, EGR, etc. Etc. And I don't want to get into thousands of dollars of replacement stuff if there is a last step I can try first :-)
