jayster0966- for your rough running. i would just move coil from cylinder 3 to cylinder 1 and see if the rough running moves with the coil. maybe do the same with the plug if the coil was not it. it could be an injector also.
as for the LCM, what year is your car? the LCM's are supposedly the same it is just the coding that is different and that can be changed by changing the ZCS or the VO depending on when the car was manufactured. i may have time to play with this this weekend. i have the euro lights already and do not like red turn signals. they should be yellow. that is how i have them now, they just look funny because the LCM is coded for NA.
