Yesterday, I was on a delivery when my car started chugging and sputtering, running on only five cylinders. After a minute and a half it quit misbehaving, but immediately the "Check Engine" came on. I took it to AutoZone where they pulled a P0305 code: #5 cylinder misfire. When I took it in today, they examined it closely and found nothing wrong at all. The Autolite Double Platinum plugs are new since January, and they were the first things I checked. The coil pack and wires turned out okay, so that leaves the injector as the final suspect. But to have it malfuntion and then work right again?
My grandfather and I think it may have clogged temporarily. What do you guys think?
