So the miss started after the service? Check the plug wires, the cylinders are 1, 3, 5, 7 on the drivers side, 2, 4, 6, 8 on the passenger side (front to back). It is not the same on the distributor. There is nothing on the distributor to adjust, there is only a cam sensor, but he cap does need to come off to verify it is line up properly with TDC. The code for a distributor that is not set right is P1345 (camshaft/crankshaft correlation error).
