If you put the fuel filter in backwards, it will collapse and clog, leaving you with no power.
As for the smoking, it depends on the color.
It is it whitish, then I would guess head gasket, and recommend you borrow a cooling system pressure tester from a place like Autozone, to see if the system hold pressure or show oscillation when engine reved up.
It is it bluish, then you probably either have gas in the oil, too much oil, or you broke a piston ring.
Changing oil and doing a compression test would be the way to tell.
If it is black smoke, then the fuel mixture is probably too rich.
That could be a bad temperature sensor, bad air mass sensor, bad O2 sensor, or weak spark, like bad wires or plugs.

If just idle clean the throttle body and the IACV and be sure the IACV mechanism isn't sticky.

It could be a clogged injector but that would show up at all speeds...

Smoke when start moving.2.5 crdi 2006 model


if it smokes when you start moving , and then clears the first thing to do is change the air filter, even if it looks clean.
i would not even start looking for other causes until this has been done.
do not run the car without an air filter to test it as this will affect the airflow and can cause problems on its own. filters are very cheap and readily available. the slightest dirt on an air filter can reduce the air flow through it and while it may not appear dirty, it can affect airflow enough to result in a rich fuel mix being burnt under power, resulting in smoke. as you get up to speed and ease up on the throttle, not as much air is needed and enough can frow through the filter giving the correct fuel mix and less smoke.

if this does not work please feel free to ask again but 99 times out of 100 a new air filter will cure smoke when pulling away in a fairly new car.

Just bought it....seems to run fine, no over-heating or smoking, 232000 miles...paid 400 bucks...owner says it is a daily driver, even occacional long distance driver.......no problems....my test drive,...


Try changing the fuel filter. If it's been there awhile it's probably starting to clog and won't be able to flow enough fuel for the heavier demands the car has when going uphill or trying to accelerate hard.

Loss of power


I would start by checking for a fouled spark plug/wire. Also, check the fuel filter. It doesn't have to be good just because it is new. Could have a factory defect.

Fuel filter on picaso 2.0 litre diesal engine


Black smoke from a diesel engine does not mean you have to change the fuel filter.It is caused by the air filter being dirty.That you need to change.Anyway if you want to change the fuel filter it is located at the front middle of the engine in a black plastic round case with notches around the top.Good luck hope that was helpfull.

Check fuel pressure you need at least 40psi to operate injectors on a 4.6 or 5.4 liter motor. If it reads below this you have a weak fuel pump and or plugged fuel filter. If everything checks out go to step two.

Step Two

Sounds like you need to replace both coil packs. And you should do the plugs and wires.

Dumps raw gas into engine


Just a few things to check. Take off the fuel filter and make sure there is no water in it. If you have put in different spark plugs than AC Delco, then change them to AC Delco. If you haven't looked at the plugs or the fuel filter, then it is way past time to replace the filter and new AC Delco spark plugs only. These places that insist that you use Bosch plugs or split fire plugs don't know ****. The Delco plugs are made especially for your engine and will out last those cheap non-working Bosch plugs.
If the fuel filter and plugs don't fix it, make sure your air filter intake isn't stopped up with a bird's nest. Happens a lot. If it still misses after new plugs, you may have a fuel injector sticking.
The bad smoke is the gas-thinned oil passing the rings and unburnt fuel smoke. The missing really bad is most likely fuel soaked spark plugs. Make sure you change the oil while changing the plugs or you will have a redo. Let us know if any of this helps. Dale
