Hi, I have a 2010 Escape 4 cyl with a cylinder 1 misfire code. 100,000 miles and code just came on. Vibration at about 50 and 70 mph and when in gear and foot on brake. Changed plugs - same code, swapped coil 1 with 4 - same code, swapped injector 1 with 4 - same code. Not sure where to go from here. Egr and intake issues would show up on other cylinders, not just cylinder one misfire I would think. Didnt know if anybody else has had the same issue. Any help would be great, thanks.
