2007 Ranger Missing
I have a 2007 ranger 3.0 with around 100,000 miles. It started missing on me, I took it to advance and it said misfire on cylinder 3, So I have replaced plugs and added sea foam to clean the injectors. It got better, came back last week which was about 3 weeks later from changing plugs and put on new plug wires. Today was first time really driving it and it is missing again. What else would I need to do. Thanks in advance.
