Early Morning Cold Problems

[BoureeOne]

My 06 F350 is very hard to start on cold mornings. 5 or more tries before it catches. Once it catches it runs very ruff. I try to pump the accelerator and it has no effect at all. I can even push it to the floor and there is no increase in rpm's at all. As engine begins to warm it starts to smooth out and the accelerator begins to work in equal amounts. While engine is cold it does not want to shift either. Once the engine is up to normal running temp, it runs and shifts like new. Any suggestions would be greatly appreciated.

Mine did this exact same thing and I had an injector going bad. Actually its done it twice and each time was an injector. I would suggest buying HOT SHOT SECRETS additive and put it in you oil. It cleans the oil side of your injectors and if you have one that is sticking it will clean it up and make it working like new. I added it to my oil and you have to put about 1000 1500 mile on it to tell a difference. I had no problems but it runs better and starts better than ever before.

My truck did this for the first time this morning as well. First time under 30* since I bought it. My block heater cord is on order, due in this week.

Are you guys that have this issue plugged in over night?

I currently have conventional oil in my motor. Will synthetic help cold starts?

What additives if any do you use in the winter time?

Corbzy- did your injectors fail? Needing all of them replaced? It seems when batteries go down these trucks have injector issues.
