No the crimps were all metal and seemed very secure. I have seen mentions of some splices in some factory wiring diagrams so maybe they are normal.

After some more testing my recent problem of the CEL and MIL coming on after driving for awhile has got me thinking it could be something as simple as the O2 sensor on the way out. It seems to always come on after driving for about 15 minutes after the car has warmed up a bit. It still doesn't explain why when I check for codes it says there are none, or the trac off light flashes and my CEL doesn't even blink. The car definately runs rich when this happens. Ox1 reads above 0.9v, exhaust smells almost like straight gasoline. Can oxygen sensors work bad when warmed up but fine when cold? I always pegged them as a failing unit.
