Slip, vdc, and RAS lights are all stuck on. It happened one morning, on the cold start it only started at half the rpms it usually does on a regular cold start. Later misfires, fixed it with new coil and SP, and lights are still on. Obviously i have no traction control either, the button is useless. Anyone got ideas what could cause this? My cold starts have seemingly been okay since that morning and have had no issues besides the misfire… ALSO NO CHECK ENGINE LIGHT. How can i diagnose this problem effectively?

 

You said you had a misfire and replaced all the coils and that fixed the misfire cause I have the same problem looking for a solution. Which coil pack did you go with? I'm looking at them and they go from like 65 to 365 bucks wondering which is the best or at least sufficient. Thank you.
