Hey all. my car starts up and idles (rough though) and the engine light is on. but for some reason i cannot see or read any DTC issues. I bought the latest obd connector FTDI. any suggestions on what i may be doing wrong. my settings in connection type says FTDI auto connect same in com settings. here is an itnitial response when first plugged. 2005 rx8 a/t. thank you for any consideration.

 

I didn't watch it, but often rough idle is related to vacuum leaks around the intake.

 

It just looks like your OBD2 scanner isn't working. If you just bought it, try reaching out to their support or checking their user manual.
