Good mornign all,

I am getting the following misfire codes but he Rover is running great!! I have swapped the coils on 1 and 4 with 2 and 3, cleared and ran until light came on again and same codes popped up for 1 and 4. I then swapped the plugs (new plugs BTW) and same scenario. I have attached a bunch of pictures of live data readings from my Bosch 1350 scan tool but I am not sure what is good and what is bad. Hoping someone that does know can take alook and aceratin what I need to look at next. In the mean time I am on my second round of seafoam treatment hoping it is just a dirty injector.

It has new plugs and coils. in teh pics below I am assumign a 0.00 on a fuel trim reading is bad? If that is that is the case maybe the fuel pressure at 37 PSI is low and I am just not gettting enough fuel in the system? But, it is responsive and does not lag though... On teh control Module Voltage reading, this was taken while the Rover was running and seems low to me... Shouldnt it be just above 14 volts when running?? Maybe that is why the fuel trim is at 0.00 in a couple of these?

Really hoping someone has experianced this and can shed some light, thanks all!!!!!
