Car now has NGK plugs and wires ( with the metal boot, sourced through NAPA, listed specific to AEG engine). I have reviewed my plug wire placement and connections too many times to count. The coil pack has the terminals labeled A,B,C,D. I have 1A, 2B, 3C, and 4D. In the link provided earlier to the Volkswagen service manual, the diagram of wire placement at the coil pack ( listed for the Golf 2.0 AEG, not sure it would matter) the wire placement showed wire 2 connected to left upper coil pack terminal, which is labeled C on my pack. I have even switched wires 2&3 to reflect this diagram, made no difference at all. It would seem most logical to me that since this problem arose only after the initial swap of plug wires, coil pack and O2 sensor that the problem must come from 1 of these areas. As stated earlier, I have checked resistance now on both new coil packs at ~ 7500 with the ambient temperature in the 30s F. I am by no means an ASE tech, but have been a mechanic my entire life (48 years) for myself, as well as the public. I again am at a loss. Any other suggestions? I thank you once again.
