Hello, I have recently fitted new Yellow jackets coil packs and plugs. Car runs fine but the check engine light aswell as TCS and slip light are on. Connected a ECU talk cable and the fault code is Code 21 ignition signal primary. I have tried clearing it and also disconnecting battery with no joy. Plugs were gapped to 0.8mm. Engine is a RB25DET NEO. Any help would be greatly appreciated. I have done a search and all results state faulty coil packs. Is there anyway i can check each coil pack with a multimeter?

  Murray has the right idea! Or just pretend you're a tow truck driver, they drive around as if it's a race track. Pads will be bedded in in no time! Or you'll arrive at an accident scene quickly...

  Sounds like doing a track day will resolve all your issues.

  The rotors only have about 5k on them so I didn't worry about the machining.

  Also, if you didn't machine or replace rotors, it will make it harder to bed the new pads properly. It is something I'll advised to do. And yes, I've done it many times before, and will likely do it again, so no judgement here if you didn't replace or machine the rotors.
