The Cascade valve is less expensive, and easier to change. under 40.00 at Geno's Garage, part #F-00N-200-798.

No, it sets right on top of the CP3, it looks like a bolt with a silver ball bearing mounted in it's head. Screws right out, has an o-ring seal.

Well I think I figured it out, it was a loose wire on the fca plug. I went out today and started her up, let it idle for about 5 minutes. I then reached down and gently took off the plastic plug on the fca, wow, she started shaking and stumbling. I did this to find out what it would run like if there was a short or break in the wire/connector. I pluged it back in and it started running fine. I then started moving and shaking the wire harness and wow, we now have a rodeo again, then she completely quit. I restarted it and it ran fine until I started moving the wires around the plug that goes to the fca and it went into round 3 of shaking and bucking, then it quit again. I got to lightly pulling on the wires that went into the plug and one of them almost fell out. The little prongs that hold the wire conector in the plug wasnt bent enough to hold itself in, I bent it a little and it works perfectlly. I shook the wires and it would not do it again. I REALLY hope this fixed it. I still have the code showing up cause I dont have a scanner to clear it yet. Hope this helps for someone else.

Good morning Jason. Go to User CP on this site and fill out your Profile and Signature. Folks here can help you better if they know what truck you are asking help for. And, in the future, starting a new thread will probably get you better/quicker help.
Back to morning brew . . .
