Hiccup Question
Every now and again my truck will hiccup (i.e. the engine basically stops for a split second) and then keep running like nothing happened. This has happened 6 or 7 times in the last couple of weeks, and the SES light has come on twice (and gone off again when restarted). Now this may be a total coincidence, but so far this has only happened when it has been raining out.
Truck is a 2000 PSD with an AFE filter mod and the GPR upgrade. Otherwise, it's stock and had a new CPS installed about 3,000 miles ago.

Sounds like the CPS (Cam Position Sensor) is getting intermittent.

If it is only occurring when wet out check the connector to make sure it is tight and doesn't have any corrosion in it.
Another possibility is the Windshield leaking and dripping down on the PCM.

was the CPS installed 3000 miles ago a Fordor International or was it an aftermarket? I had one i bought from O'reilly Auto parts start to go bad in less then 3,000 miles. i replaced it with the new $15 grey one from ford, all is good now.

I really needed a replacement today so I went to a local stealership (Freeway Ford in Denver) to see if they had one of the gray B units. The parts guy had no idea what I was talking about until he punched in the part number and up it came ("hmmm, the B part number is a lot cheaper than the A one"). He ended up ordering me the part from another Denver dealer and charged me $37. Not bad for getting it the same day.
It remains to be seen whether this is the problem, but I'm very happy to have a $37 new-and-improved CPS sitting in my glovebox, just in case.
Thanks for all of the reponses posted here - that's why I love this forum.
