Misfire before and after tune up
I have a problem with my S500 I purchased this car a month ago and the car is in excellent condition. One day on my way home from work I accelerated to go around someone and when I got to the stop light my check engine light came on and car had a misfire as soon as I got home I scanned the code and I got multiple misfires 1-4. So I changed all four coil packs all 16 plugs and wires the MAF and passenger side 02 sensor. Drove the car around the block and check engine light comes back on and flashing. Cleared out the code and drove again noticed that when it hit 3200-3500 rpm the light came back. Can someone please help me out point me in the right direction.
