Changed out the spark plugs and coils to the 2 step colder & Delphi coils. I then went out and did a small 2nd gear pull from 3-5k rpm’s and the car felt amazing! I figured I would go straight out to get a full 2-7k rpm log in 3rd gear and ended up running into the same issue where it fell flat after about 3k. The following codes re-appeared: 29CC - DME: Combustion misfires, several cylinders. 29CE - DME: Combustion misfires, cylinder 2. 29D1 - DME: Combustion misfires, cylinder 5. I then pulled over and cleared the codes and drove around casually for a few minutes then tried another small 2nd gear 3k-6krpm pull and the car felt amazing! So, I’m not sure why that 3rd gear 2k-7k attempt is giving me issues but the two 2nd gear small pulls from 3k both felt great.
