06 rough idle, missing, smoking???
I have a 06 that just started to idle rough, miss, and smoke(light grey until you rev it then it turns fuel black) temps in the 50/60's
Run's bad and will hardly get over 40mph.
I have no check engine lights on at all. I plan to hook up a scanner to it tomorrow to see if it has any codes.
Today I changed the fuel filter's thinking it was water in the fuel. I drained the one on the frame rail and got very little water and some trash that kind of looks like rust. The filters looked good (They only have 2000 miles on them if that).
That didn't fix it.
Truck has been running great other then a no start when warm/hot(not over heating)
I have been fighting this no start when warmed up issue for about 5 months and this is what I have done so far. I have replaced the icp, ipr, fpr, battery's, starter, both fuel filters, and oil.
Until now I was thinking it was the stc fitting and/or the dummy plugs. (But I don't have anyway do the air leak test)
This is my tow rig and I don't use it but about once a month, so I wasn't in a hurry to get it fixed.
I have searched the forums and have some Ideas.
My question is do you think the 2 problems are related?
What should I start with first? I was thinking checking the FICM first. I will have to do a search for the proper why to check it.
Is there something else I should start looking at first instead of the FICM?
