Enging codes said O2 Sensors so I replaced the four that it said. I also replaced the spark plugs with bosch and the spark plug boots. None of this helped my idle problem. When it is below 50dg's it idles rough and wants to die. When it is worm out it runs great but it idles low and has jumps in the rpms. I love this truck but I hate if because of this please help.
