Misfire Cured?

My 2005 F150 crew had a misfire when under wot. I had been putting off the diagnosis fee for months, but I finally bit the bullet. Found out my number 3 coil was bad and the number 3 cylinder was dropping out. Dealer swapped out coil and truck runs better now. Still have to get plugs done. Truck has 88000 miles. Already had the cat replaced and didn't want to go through that again.

Who wants to tell him that he could have had the codes read for free at most parts stores?

Having the code pulled and having it diagnosed are two very different things. A good shop will stand behind their diagnostics.

When you do the plugs make sure you use silicone grease on the boots to prevent moisture and burn through of the rubber.

When they put it on the machine the number 3 coil was dead. I don't know how I didn't blow her up.it was running like crap, for a long time. I have full confidence in the dealership where I get my service done. I am more than likely not going to do the plugs myself.
