Engine Performance problem
1999 Ford Ranger 6 cyl Two Wheel Drive Automatic
My Check Engine light came on 2 weeks ago and I did a scan, p0306 and p0174. I relize 306 is misfire cylinder 6 and 174 is a lean code but im lost where to go now. I have replaced the coil, spark plugs, wires, DFPE sensor, egr valve, Replaced injector 6, Cleaned MAF and I am still getting these codes. I am absolutely stuck now and need a guide on what to do next or what possiblities would cause these codes, and are they related some how? Also I have been getting the p0306 for awhile now but the 174 started to come when I added my new Cold Air Intake, and yes I have tested for leaks and there are none PLEASE HELP ME! Thanks!
