I have a 2000 Navigator with probably about 108K plus miles on it. Back in June I went to some small shop and I got a tune up done on my car. They did it, and it ran like poop, and later realized they put the wrong parts in (it wasn't for a 2000 Navigator). They supposedly fixed it. Now, a few months later, I have had 2 incidents where the " Service Enginer Soon" light comes on. The first time, there was a cylinder 3 misfire, so I took it to a dealership and paid almost $300 to get the coil and spark plug replaced. Now #1 is misfiring.I wanted to know, should I go back to the guy who did the tune up, a friend said this should not be happening since I just got a tune up done.
