2010 Dodge Ram 5.7 Hemi. 136,000 mi. Bought it a few months back with 131,000 miles.
Seem to be generally maintained with good records but nothing to indicate when the plugs were last changed.
Performance slowly and steadily deteriorated over last month or so, until it finally started stumbling and sputtering couple days ago and the check engine light came on. Flashing at first and then steady. Hooked up the code reader got p0303. I know that could be a lot of different things, figured I'd start at the plugs. I know they need changed, for sure. But does anyone with more plug guru-ship than myself think they're in bad enough condition to trip that code?
Any help or insight would be appreciated.
