Rough idle, smells of gas, blowing smoke (white from exhaust) and very little power?

Had the fuel injectors replaced. I was told that was the problem, about 3 months ago. The mechanic also said that the head was blown, which it is not. But it started doing the same thing again a few days ago.
Crankshaft hose needs replaced also but cannot find the right one. The dealer tells me it's discontinued.

Hi,

Are you getting a lot of white smoke from the exhaust? If so, check to make sure the engine coolant is getting low. When coolant enters the combustion chamber, it burns white. It is possible you do have a failed head gasket.

Do me a favor. Take a look at this link, see if anything mirrors what you experience:

Also, I'm not sure what a crankshaft hose is. Can you explain?

Let me know.

It's the hose on top in this picture. Could also be called PCV hose?

Hi,

Yep, that's the PCV hose. LOL You lost me with the crankshaft hose. Were you able to review the link I attached above?
