So far so good! One thing that wasn't mentioned, the last time the system went crazy I noticed (just before it all started) that my voltage was rather high (around 15-16) First the ABS/INOP light, then the turn signal indicator, followed by the meth kit turning itself on at idle ... A few miles down the road the issue seemed to correct itself.
It wasn't untill the following morning that I popped the hood and found the cable to be kind of loose. I have put about 60 or so miles on the car since both terminals were cleaned and tightened and no issues! I have been told it may be a good idea to use a longer bolt on the cables since optimas seem to have an extra "lip" or platform that restricts the amount of threads that are usable. I dunno, keeping my fingers crossed!
