In my truck it doesnt matter if it is warm or not but when i am idleing or when i am driving at a steady rpm it feels like the whole truck shuts off then comes back on at about 200 rpms. And the last time it did it it threw a ses light. Could this be my cps going out?

 

To be sure and at least closer to sure, have you codes read. If it tripped the light, there is a code. Could be the CPS and ford has a free one for you with a recall. So questions are arising about the new one's and I for one am keeping my old black one. In you case, might be worht the gamble.

 

yep i'd would definiely change that out ASAP!!
