'01 ranger started missing and gave P0302 code (misfire cylinder 2). Changed plugs and wires. Still getting code. Started getting p0306. Read that cylinder 2 and 6 are paired and fire at the same time so I figured the coil pack was going and replaced. Now getting p0301 (cylinder 1). Engine misses at all speeds and loads, but SEEMS to get worse the longer I drive. When the truck runs right, it runs good so I don't think it's a compression problem or it would be constant, but I could be wrong. I want to look at the cam position sensor, injectors and maybe the ECU, but would like a professional opinion.
