I have done some searching, but I can't find a situation similar to mine.

It's an 05 manual RX8 and when I am driving... usually after a mile or so, my DSC will turn off. It will illuminate the "squiggle" light and remain off until the car is off. Then after driving some more, same thing happens. I have no problems with starting the car and the DSC only turns off after driving for a little bit. The speed or RPMs does not seem to play a factor causing it to turn off.

I have just replaced my cat and the 2 sensors. Is there anything possibly relating the two? As it happened right after they were replaced. The wires/coils/plugs have less than 4000 miles on them as they were replaced recently. Also, my battery is good and was replaced fairly recently as well.

Anyone have any suggestions on what I should check on?

 

I recommend you have the ABS/DSC module scanned for codes.

 

Yeah, was trying to avoid a trip to the dealer if possible... but it's got me stumped.

 

The dealer isn't the only one that can do that. You can probably find someone or another shop that has a scan tool that can read ABS codes.
