I had a little problem with the TL the other day. I parked the car for two hours and when I started it up to head home, it didn't sound too good. Because my check engine light and TCS light was on I went to autozone and had them check for codes. P1399 and P1738 came up. Well it turns out I just had a miss fire (P1399), and after I replace the bad coil. She is back to normal. Thanks to acurazine and it's members I was able to find out what code P1399 was. SO THANKS TO EVERYONE! I just wanted to make a posting about my two codes and maybe help some else out in the future.

Oh... P1738 deals with the transaxle. (I think) After I cleared the codes, the TCS light also went away and I never had any problems with the tranny.
