Could this happen?
Short story: driving at highway speed, car starts to skip and stall. Thinking there's an issue with CPS. Get home, check to find out the CPS bracket is loose. (!) Tighten it up and think all is right with the world.
Next time driving, engine light starts blinking then sets 2 codes. P0303 (misfire in cyl 3) and P1313 (bad one - possible cat damage - unspent fuel). Check coils, oil in the plug wells. Take care of the valve cover gaskets, clean the coil boots and contacts, change the plugs, make sure to switch the cyl 3 coil with the cyl 2 coil, clear the codes, and off for a test.
Now, sets P0304 (misfire in cyl 4) and P1314 (rear cat this time). Do nothing but clear the codes and take another test ride. Now back to P0303 and P1313.
Got to thinking (dangerous) it may be the CPS anyway - it's the original, so it may be iffy. I have another on order.
Question: Am I onto something, could an unstable signal from the CPS cause this weird chain of events? I'll update when the new CPS is installed.

Both my AJ16's dropped the CPS at 160000kms (100000miles), for no apparent reason.
BUT
The 3.2 still had female moments, and I eventually found the 2 pin loom connector, in that STUPID bracket on the front of the timing cover, had filled with oily crud over the years. Removed it and sealed the unused holes, cleaned both plug and socket, sprayed some lube and refitted, 5 years now, sweet as.
ALSO
If that CPS has rubbed on the crank star wheel, when it was loose, its probably past its replacement time, they dont like that treatment.

My experience with these hall affect sensors has shown that they will will still work properly with a gap way out of spec on the open side, but they may exhibit signal loss as the RPM increases.
