What were your symptoms?
I'm tryin to find out what is wrong with my truck without dumpin tons of $$$
eventhoough it grows on trees

 

Very similar to a bad injector at idle. Usually a bad injector will continue to miss and smoke, with the FCA, it usually will clear up and then start smok'n and miss'n again.

 

Try draining fuel filter canister, change filter, and put in about an ounce of conditioner with a good lubricant in it in canister. Put a double or tripple dose into tank. Use that tank if problems subside then next tank run straight diesel, if problems come back its the FCA that is sticking. My truck was acting up and smokin after I got dealer to install new sticks and they said it was the "after market injectors causeing it. Because they dump all that extra fuel in and it cant burn it all at idle". Which was the same problem I had when I took it into the dealer. What I discribed is what I did, changed the FCA. No idle smoke and smooth sailing since. Also if ya need to change FCA very easy to do but check local diesel shops for it Dealer/250 bone local part shop 90 bones

 

Ok, I will ask. What's an FCA?

 

FCA stands for Fuel Control Actuator. Its on the back to the cp3 pump about the size of a C battery and priced like its gold. It controls fuel flow in the injector pump.

 

thanks.

 

come to think of it my truck does that but with no smoke....unless wot then will smoke like hell for a second. pretty sure i need one or two sticks but i cant touch it since i quit the dealership (still under warranty ).
