97 250 psd code problem

[Hartswelding]

I have a 97 F250 Psd, this morning it was around 18 degrees and i let the truck idle for about fifteen min before taking it to work. On my way to work the truck kinda felt sluggish and was downshifting alot, and then the check engine light came on. After getting to work, i checked the codes to find a P1211 ICP above or below desired and a po344 cam sensor circuit intermitten code. After checking the codes, i drove the truck again... no check engine light or sluggish behavior.. Could someone help me shed some light on this situation because i dont want to continue to drive this truck if there is a problem. thanks alot

I had a lot of random running issues, intermittent missing, run good one day, terrible the next. I had replaced the CPS with a POS aftermarket(BWD brand) I had in the glove box when replacing my fuel pump. Ordered an original International black CPS from DieselOrings and has run great ever since.
