# 3 cylinder began to mis fire. According to manual plug change was in order. When in the process of plug change found #3 plug fuel fowled. Changed all plugs. Ran on all 8 for short period. The truck has coil over plug configuration. Changed boot on #3. Still wanting to fowl on #3. Swapped #1 coil with #3 coil and added new plug. Still having mis-fire on #3. Problem seems to start at beginning of acceleration ( low to mid RPM). Question is, could this be a problem with the computer or chip?
