Alrighty CEL came on and I went straight to autozone. Multiple Misfires code appeared, he never said in which cylinders but he did say check the the spark plugs, so i did when I got home. The plugs looked healthy however I was not able to check the gap. After I put it back in the code remained off but, the idle felt a little stronger (may have been paranoid) so I decided to try some accelerations to see if the performance was fixed or not. This only happened in 1st gear between 4500 rpms and 5k rpms it felt as if the car lagged. However, as soon as it hit 5k it felt normal again and was doing fine through gears 3. What could be the issue? The gap? Assistance please...
