Bump......................

Dropped off at the Dealer this morning for "exploration " to find the Problem...STAY TUNED!

Good luck with the Dealer, hope they can do what needs to be done!

Thanks, Bill...they put in a new Battery (Motorcraft 850 Super Duty *which is ALL I've ever run...and told me the CHECK ENGINE was GONE!) I went to pick up the car...started it up...CHECK ENGINE light was ON as soon as I fired it up!

Since then they took time to chase electrical connections. They have now FOUND that the PCM is NOT sending ANY Current to the Camshaft Sensor Unit Bank #1 that I have had replaced. But then again...the question is...If there is NO current going TO that sensor...then HOW is it "intermittently" throwing a code??!!

They had me check with my Tuner to make sure the current WAS NOT shut off in the tune...which of course it wasn't. NOW...we are doing some driving and Data Logging to see if the dealer can turn ON the current to the sensor using their IDS. *WITHOUT messing with the Tune!

ALSO...I'm on a SEARCH for another PCM...in case THAT is the issue. Hopefully @mustangeddie can come through for me?!

Typical Dealer, don't know how to troubleshoot electrical issues. They just want to change parts until they luck upon what fixes the problem. Good luck finding a PCM that matches your vehicle.

You are 100% CORRECT Bill...we SURE DID have it NICE 22 years ago @Team Ford, though...didn't we??!! THOSE were the DAYS!

[Black Terror]

Yes, and had Carfixer, and others to help troubleshoot problems.

Team Ford lost all their good people when they stopped them from working on our vehicles unless you went thru front counter. Today, it is a part changer Dealership. Sales and Service have gone to pot. Pugmire is the same way. They did things to my Vehicle that I didn't authorize so I use someone else for service, unless it is a Recall or Warranty item.

Hey bud, I've been down this road. The alternator is the issue.

I've heard this, as well. And I ASKED about this with the Tech...he says the Alternator "is working fine..." I ALWAYS WONDERED due to The Trilogy needs the alternator turned AROUND backwards.

What choices do we have on Alternators...that are NOT made in China?
