It’s started to miss fire after I change my mufflers (temporary). I’m running with test pipe, stock HR Y-pipe that’s welded straight pipe. It only misfire early when i turn on the car and drive right away. it won’t let me push the much power when i press the full pedal but the issue stops right after a little bit amount of time (1 to 2 min), it will run normally fine at the end. Should I be worry about it and take it to the shop and get it repaired again about the misfire?
