I have a 02 F250 it will start up fine even in cold weather without needing a plug to stay warm.
While driving at slower speeds it will die, doesnt matter under load or not, while at highway speeds (Above Aprox 35mph) it will hiccup instead of die and flash check engine light. Has always restarted.
I have replaced the CPS, everything seemed fine, but living in Olympia Wa, until the next rainy day. Does the same thing. Dies or hiccups but always restarts.
Got CPS from NAPA. How often do they come bad straight out of box?
What else might this be? Ive heard Crank Shaft sensor, IPR,.
even bad fuel tank sock
I have had it coded even with the engine light on and no codes present.
I have checked the harnesses and pluggs all over the engine compartment nothing noticably wet or broken. Where are the problem areas and maybe im just over looking?
I have even heard bad ignition switch? Just trying to fix while keeping cost down only averaging 2.5 days a week making bills but not a lot extra.
Any thoughts, comments or ideas greatly appreciated!!!
