YES, you have to investigate what is throwing your valve timing off. That could be anything from a vacuum leak to clogged injectors, bad plugs, sensor ect. Have the car analyzed to find the cause. There can be many causes. Good luck

The firing order is believe it or not 123456. The cylinder numbering orientation is 135 on the rear bank which is closest to the firewall and 246 on the front bank closest to the radiator that's reading from left to right

when in the driving seat the bank 1 is on your right hand side bank 1 has cylinders 1,2,3,4. 1 being close to the headlights, bank 2 is the left hand side 5,6,7,8. 5 being close to the head lights. I am not sure the but I think the firing order is 1,3,7,2,5,6,4,8

From standing in front of car and facing engine:

3.1L and 3.4L OHV V-6: The cylinder location is from left to right (rear cylinders) 1,3,5
(front cylinders)2,4,6

The coil terminals from left to right: 5,2,3,6,4,1
Firing order 1,2,3,4,5,6

3.4L DOHC V-6: The cylinder location is from left to right (rear) 1,3,5 (front) 2,4,6
The coil terminals are from front to rear 5,2,3,6,4,1
The firing order 1,2,3,4,5,6

3.8L V-6 cylinders left to right (rear)2,4,6 (front) 1,3,5
coil terminals front to rear 1,4,5,2,3,6
firing order 1,6,5,4,3,2

P0302 Cylinder 2 Misfire Detected
P0303 Cylinder 3 Misfire Detected
according to this fault codes first mark ignition coils
3 ---------------- 6
2 ---------------- 5
1 ---------------- 4
RB-------------LB
this right banks and left bank, please remove Ignition coils with lids and spark plugs from right bank and swap with left bank, if fault code change as
P 0304 Cylinder 4 Misfire Detected
P 0305 Cylinder 5 Misfire Detected
P 0306 Cylinder 6 Misfire Detected
You can Identify it's a faulty ignition system then next swap ignition lids from ignition coils be careful each coils have two lids one short and other long bit deference and when you remove and fix it to the car keep in mind correct order because each coil two different fire for two spark plugs don't mix up, if you mix it can create the fault code.if you detect any fault ignition coils or spark plugs or lids replace that and also whether god or bad recommend to replace spark plugs, find the right that's most important thing, if this way couldn't found the any ignition fault next step is check fuel presser, when the engine running fuel presser must be around 4.5 bar without engine running must be 4 to 6 bar if the fuel presser too low need to check two different things one is fuel pump other is fuel injectors, in this case you can swap injectors from right bank to left bank and find is the injectors leaking, if not leaking faulty fuel pump.is this information helped you? if yes please leave a comment,
