I was wondering what the symptoms was for a bad Fuel Control Actuator? my truck has a lopy idle. would this be one thing or not? my truck a month ago threw a p0121 code would this be anything related to a FCA,but that was a month ago and i erased the code and it never came back? need some input guys thanks.

 

A bad fca likely won't throw any codes. when mine puked, the symptoms were intermittent stutter at idle, the engine would sometimes die when I came off the throttle, and I had to tickle the throttle to take off from a dead stop. Super easy to replace though...takes longer to drink a beer!

 

A loping idle is a symptom of bad FCA.

 

Ok ill start there i just hope its not my injectors.

wheres a good place to buy a fca and the cheapest place?

 

Give Todd at T&C diesel a call! Just google him!

 

Cummins...$95 for the last one I bought...

 

Is cummins a cummins brand or is it a bosch brand for the fca.

 

Cummins uses Bosch components for their fuel system...if you buy at Cummins, you get Bosch.

 

Ok thanks and also I talked to Todd at t& c diesel and he said i should start by replacing my fca and cascade overflow valve. he said it s probably not my injectors.
