You may have a failed ignition coil. If it is gad, you can replace it for around $36 to $70. If you replace on, you should change them all.

My 2007 did the same thing. Switched coils, still missing #2 cylinder. Put in new fuel injectors and runs like a top, no codes, and the mpg went up significantly. Did it myself in about 30 minutes. Injectors about $130 for all four.

Hoosierdaddy4 , Have you ever serviced the fuel injectors before replacing them? They can go bad, but after so long, they do need to be service. Good fix buddy. Thanks for the heads up. Hope you kept the old one, you should get them cleaned and that way you have a spear set to fall back on. My parents were from the depression, and dirt farmers. They NEVAER threw anything away. When I was tasked with emptying out the house, sheds and garages after they died, it was a chore. But keep them in case.
