Rough cold start and idle
Im sure this has been posted a million times here but im posting this at work and did not have much time to read through the posts... here goes
I just recently baught a 99 7.3, On cold startups the Engine shakes and knocks pretty bad. After 20-30 seconds the shakes and knocks go away. When i go to drive the truck it is very sluggish and has no power, after about 3 or 4 mins of going down the road the truck "fixes itself" and drives much better. Although you can still notice a power loss and hesitation. Ive noticed you can let the truck sit running as long as you want for it to warm and it still has the sluggish/no power problem. It is only when you get it down the road a bit that the problem gets better.
***Note*** during all this the truck DOES NOT smoke black, white, or anything.
The truck has new batteries, alternator, cps, and the fluids look fine.
Where should i start in trying to fix this problem? thanks
