OBD2 scanner came in the mail today, so just finished checking out the codes. Said there was 4 old ones and one new one, "p0500, p1518, p1590, p0136 and finally p0350." Assuming p0350 is the newest one, this makes a lot of sense. P0350 - Ignition Coil Primary/Secondary Circuit Malfunction. What should I be checking to remedy this CEL, perhaps one or more were duds? they came off a 2001 V7 with 115ks on the clock. I may not be the greatest DIYer but they all felt in place correctly etc.
