Engine stalls at idle/cuts out under load

[ty2wheel]

I have an '02 F250 with 200k on it. It runs very well, no smoke, and has a new turbo on it. It has an Edge juice module and evolution controller. I had some rough running problems and inspected the cam sensor wiring harness and replaced with a new one (not Ford, Standard brand). The truck ran fine after that.

Now, almost always when raining, the truck will intermittently stall at idle and/or cut out under a light load. It has done this when dry but not near as bad as when wet. I usually do not get the check engine light on but did this weekend. I grabbed a scanner the following day and as usual, no codes, no freeze frame.

I am frustrated and don't want to tow under this situation. I am in the Sacramento/San Francisco Bay Area in CA and need a good independent shop to take it to.

I have another cam sensor to install but it has only been 3000 miles since change. I also have the recall but am reluctant to take to Ford due to programmer.

Any suggestions or referral?

1st - if the SES light came on you do have codes stored. If your scanner isn't reading them, it just means its not compatible with your PowerStroke. You have to use a high end scanner like SnapOn or Autoenginuity.

2nd - there are issues with windshield leaks, which let water leak down on the PCM and/or GEM module (above the fuses) - check to see if you have any dampness up under the dash - if you do - it might explain your problems.

Thanks. I will definitely check for water under the dash and check into a better scanner. I appreciate the help.
