I know my FICM is getting weak, because my Edge Insight shows that it dips down to 46-47 while driving, and it is supposed to be at 48. On start up, it dips down even lower. This morning when I started it, it didn't start right away, took three separate tries to start. And when it did start, my Insight was showing 43 FICMV and beeping at me. So I know that is shot.
My question is, could a weak FICM be causing cylinder contribution problems. I have noticed lately that when I start my Pickup after it sits for a while, or it is cold out, it runs rougher than normal, and sets off the cylinder #2 contribution DTC. It is always number 2, so I am leaning towards a bad injector, but just curious if it could just be the FICM. I plan on having the EGR deleted, update the STC's, and a new oil cooler if I ever get time off of work, and want some opinions to help decide if I should go ahead and get new injectors while it's apart.
On that note, what is a good FICM, or a good place to get one?
The pickup is a 2006 F-250 with 81300 miles. Thanks for the input.
