Smoke out of exhuast is white... but later when driving leaves a cloud of grey/blue smoke... can have moments when its fine,no loss in power or water... has lost a little oil.

Horrible rough idling No accelartion Lost of power Changed spark plugs Changed coils Changed intake manifold gaskets It then stalled while driving on highway Had it towed home Any suggestions greatly… 

Theres a small tubbed line at the back of the engine. One side is hooked up to intake manifold
The other end is kust dangling it look like a vacuum line going down around the knock sencer area.

I thought i needed a new starter because it wouldnt start, replaced it and no crank. I put my steering column all the way up and its cranking faster than ever before, but its not starting not even try… 

Cranks strong but no start. Is getting fuel and spark. Security sys indicator lite does nothing so dont know if its armed or not?
