P0301 and P0316 Fault Codes - 2004 Mercury Monterey at 86,000 Miles

Model: 2004 Mercury Monterey Fault Code: P0301 Posted: 2011-09-18 18:24

Before the Malfunction Indicator Lamp (MIL) illuminated, I noticed a rough idle and difficulty maintaining speed under load around 40 mph. I'm looking for possible causes of the misfire (P0301) and the crankshaft position sensor issue (P0316). Additionally, what is the most straightforward method to access the No. 1 cylinder? Any advice or troubleshooting steps would be greatly appreciated.
