P0352 and TCS issue
 

I was frequently getting the p0352 CEL for Ignition Coil B Primary/Secondary Circuit Malfunction and so last week I replaced coil pack B, #2, the closest to the driver.

The light came back on today while between 5500-redline.

Along with it, at 7400rpm, my slip indicator light came on, TCS turned itself back on, and then back off when I shifted to fourth.

CEL just shows p0352.

What the hell is going on. I have a trackday tomorrow and can't help but feel I'm screwed. :iono:

Car is running an OFT Stg2 UEL E85 tune.

Wait shit. I might have replaced the wrong one. So many sources saying different things.

Confirmed. Did four back to back 3rd gear runs with no DTC or Slip light.
Car is back to running awesome.

The coil pack I changed for the fix is THE ONE CLOSEST TO THE FRONT LEFT DRIVERS SIDE HEADLIGHT

I just got this code today and it seems like O have a lack of power. Did yours seem to lack power as well or did you just change it to get rid of the code? Thanks for the info!
