So it only misfires when a certain load is on the car.
So I changed all my plugs and changed 2 older coil packs that had some corrosion. I also did injector cleaner. I will be doing a throttle body clean this weekend so I can rule that out as well...After all this ...still misfiring but car is driving better
so I did a VCDS scan and theres no fault codes...however when I did the advanced analysis it showed misfire on cyclinder 1 with no fault code...

any idea whats the issue?
mileage is only 130k
