Engine codes tonight P0300, P0302 & P0304
I had these all come on tonight at the same time.
Car ran rough at low rpm at every stop. At times once up to speed it would smooth out, but not all the time.
What would cause just #2 & #4 cylinders to misfire?
2007 TL Type S at 137,000 miles all services done when needed.
TIA!

it could be a lot of things so you have to rule them out!
1. Have you done the 105K service with the timing belt and valve adjustment?
2. Which fuel are you using?
3. Did you recently fill up with gas?
4. Swap the coil packs first from cylinders 2 and 4 with other cylinders and see if the problem moves with the coil packs.

It's the auto and yes, all services are current for 137k.
I did just fill up Friday evening and always with premium. I'll check my receipt to verify just in case as the timing of just 10 miles into a new fill up could have caused it.
