I have an 05 Escape 3.0, purchased new, never had a problem, serviced regularly, 45k miles. I had purchased a Code Scout 2500 by Autoxray code reader last year for another car I had so I used it on my Escape because the engine light came on and was running poorly. It came up with a P0354 Ingition coil D primary/Secondary circuit error. After reading many of the postings on here I determined it was the front left coil pack, cyl 4. I swapped the front 3 coils several times and watched the error follow the cyl 4 coil to P0355 and P0356. I purchased a coil from NAPA and replaced it and the spark plug. It made the engine run better but the code just won't clear. I have even put one of the other good coils back in cyl 4 but makes no difference. It is now running rough, poping back through the air intake and maintains only the one same code. I unplug the wire to the coil and it makes no difference. I have even disconnected the battery and moved the new plug to a different cyl. Please, any help on this would be appreciated.
