Crankshaft sensor???
Can anyone out there help me. For the past few days the truck has been idling really rough but not all the time. I can sit at a light and it will idle fine. drive to the next light , stop, and then it bucks like hell rpm's dipping below 500. once I get off idle it rins fine. I have also experinced stalling about three or four times in the past week but always start's right back up. now when i slow down to a stop quickly the rpm's are all over the place 800, 300, 500 feeling like it is about to die. Has anyone experienced this? I think it is the crank sensor but not 100%. If anyone has experienced this let me know.

I had a custom tune done here at a local shop. The thing is it does not akways idle bad. I can drive some short trips and it will idle fine. It seems if it was an air/idle issue it would be all the time. It tripped a code last night so I am gonna have that code pulled today. as soon as the check engine light came on it really idled bad I had to brake and rev the engine over 500 rpm's just to keep from stalling at every light.

I know when I had my 04 cammed crew cab, that it pulled a move like this on me twice. When I would sit idle or just off idle it would run rough as hell, sound like ****, and buck RPM's like crazy until I got it moving good. Seemed like it did it mostly in first gear at low rpm's. Run almost like it was reduced power mode.
I checked everything, never thru any codes, but turned out to be a bad plug wire. A header burned it up. Put the stock plug wires back on and it ran fine. I know it sounds like a simple solution and it might not help one bit, but it would be the easiest to check.

Contact Cleaner for electronics works well or you can use a MAF specific cleaner. Not sure if you have one but when my Idle air Control (on TB) would get dirty it would act in a similar manner.
