P0304 Misfire cylinder 4
My '08 DTS has gotten a new problem for about a week or so now. I have been driving the Seville so it hasn't been too bad for me. Anyway I am getting a P0304 code and the engine runs rough for about 5 minutes or so. And then it seems to smooth out after that. I am also getting Service Stabilitrak and Traction Control on the dash. Can the misfire code cause the stability system to be affected? I am guessing yes. Doesn't the stability system and the traction control cut out cylinders to keep the car steady? I will be calling the dealer tomorrow as I still have the Powertrain Warranty to fall back on.
I am posting this here as well as the DTS and Seville forums. Need as many eyes as possible to see this post, thanks
