- Depending on location in the spliced ignition voltage circuit, a slight resistance can cause a misfire or a crank/no start concern. A voltage drop test on the circuit will pinpoint this condition.
- A slight to moderate resistance on any IC circuit can cause a misfire before DTC P0351-P0354 sets.
- Extended engine cranking time, may foul the spark plugs with excessive fuel.
