What color is the smoke? Could be engine oil caused by a bad valve seal. Shaking could be due to fouling plugs from the oil. Need to pull off valve cover and replace seals. Need more info.

I fitted new injectors on np200 1.5 dci, now it has hard starting have to tow start or use quick start.then it produces a thick white smoke when it starts.


Thick white smoke often means something besides gas and air is getting into the cylinders. Possible blown head gasket, holed piston, etc.

Engine running bad at idle


There are several causes for this, including the above.
Check the spark plugs and coils/wires. Lose or worn parts can cause this. If the spark plugs have thick black residue, you have an oil leak. A flat black powdery residue is too much air. A thick crusty white/yellowish residue would be a coolant leak.
If it is blowing blue or white smoke when running, the you have an oil (blue) coolant (white) leak that needs to be fixed. Normal smoke is grayish in color.
Check all the vacuum lines as a leak may be the problem.

I have a 30ltr TDI quattro that smokes when it idles for than a few minutes


This car doesn't have coils and wires, it's gasoil. The most likely reason is the piezo injectors are worn. The best way to test is with VCDS
After an overnight stationary period drive the vehicle with cold engine between 1200 - 1600 rpm till the complaint occurs. Constantly read the measured value block 13 and 14 for the smooth running control in the engine control unit. The values of one or several cylinders should noticeably move to positive.

modified injectors A8: with 3.0l, 4.2l TDI from: WAUZZZ4E*7N016685
Replace the injector with the highest deviation and all injectors produced between 1.3.2006 and 30.4.2006.
Example of production date: 060304 stands for 4.3.2006
vcds go to address 01 measured values below

White smoke from the tail pipes, rough idle in start up minimal driving will stop smoke and rough idle


i think you have a water leak maybe the head gasket is going bad any way gasoline produces water and is normal with cold weather.

After my 2005 dodge magnum sits (lets say overnight) it runs rough and produce white smoke. After several minutes the smoking and rough idling stops. What causes this and what price range to get it fixed


White smoke is a sign of water/condensation (due to the coolant additive)......worst case scenario, you have a head gasket leak (minor at this stage), or you simply need a tune up......as white smoke on cold start up could be normal...has it just started happening, or have you only just started noticing it ???

When was the last time it has been serviced (plugs, oil etc)

2006 Kia Sorento 4X4, Diesel. Starts right up but runs "rough" (more vibration than normal and valves rattle at low revs) and produces great deal of white smoke until engine heats up (after about 2-3...


i would check all the basics like spark plugs and check for vacuum leaks around the intake manifold.With a can of 2+2 carb cleaner while engine is running --if idle goes up or down that is were your leak is--
check egr too, Lee

Lexus ES300 White smoke out the exhaust no milky substance in oil


It could be the intake gaskets or even still the head gasket. How about the coolant ? Did you refill with same type coolant ? Have you noticed if it's thick and gooey ? mixing coolants will sometimes produce a thick gooey coolant that clogs up the cooling system. If the car ran hot it could also be a cracked head or block. Warped heads also. Somehow the coolant seems to be getting into the cylinder(s).
