Need some Advice
01 Ranger is showing the following codes
P0301 Misfire in Cly #1
P0401 EGR flow insufficent
Have replaced plugs and wires and new EGR value, still shows code after clearing and run time. What else should I look for? Am taking to a dio shop Friday and hopefully will get more details that the Advance auto check. Any advice welcome and appreciated.
