Driving on highway check engine light came on and engine started missing and car shaking; pulled in to Ford dealer in next town; diagnosis said could be this or that they could not figure it out but got car running smother; we went another 300 miles to our destination; took car to local Ford dealer; replaced spark plugs and upstream O2 sensor; took it home; still ran rough seems like it is about to stall an a light or sitting in traffic; took it back; they had it for 3 days; mechanic drove it; could not figure out what was wrong and said they thought it was ok because mechanic could not make it drive like it was mis firing or anything unusual; drove home and it immediately started acting like one cylinder was mis firing. Am going to take it to a repair shop that is highly recommended and let the see if they can find out what is the matter.
