ASK A DODGE RAM TECH!
Ive got a 2010 Dodge Ram 1500 SLT with the 5.7 Hemi and 188,000 miles. The code Im getting is P0301 for cylinder 1 misfire. Only starts to misfire when you really get on the gas or just under load pulling a hill. Cruising around or even at an idle the truck is fine. We've changed the spark plugs...
