Sometimes the engine light will come on then check fuel filter (which i have changed)the car runs uneven, after driving 20 mins anti pollution light comes on , however there is no problems or are very small in warm to hot weather
I had a problem with "Unblock diesel filter and Anti-pollution fault". After reading a few answers for this I decided to take car into the mountains for a good workout. Usually my trips are short and often therefore the exhaust was not getting hot enough to burn off the diesel residue in the Particle filter. In 40 mins of 3,5000 revs mainly in 3rd gear nothing showed up on the computer. Think this problem is sometimes caused by the engine not getting hot enough for long enough.
When the light goes on, keep the car running while you go to an Autozone, Advance, or Oreillys autoparts store for a FREE scan. The anti pollution system is different from the fuel system and easily can cause your symptoms
Obtain the Code number and you can decode it at the store or check online. Usually the fuel filter, if monitored at all, would only reflect a pressure variance from normal in the fuel system. This is not a pollution part.
Most likely someone guessed that the uneven running was due to a fuel filter. In a short time, this had no effect in removing the pollution light.
It did not hurt to change the filter, it just did not solve the problem.
Get the scan while the light is on. You are ahead of things by doing this because many things are not monitored by this system and you can start by fixing the things the warning light tells you about. It may fix everything by doing this. Only after the parts recommended are changed AND the warning light is cleared off the computer will you have to troubleshoot anything that was missed.
I hope my solution is helpful.
This light means that the engine control module has detected a fault in the systems operation, what you need to do now is have the system "scanned" for a fault code that was set in memory when the control module turned on the light. You will seldom feel any difference in the way the car runs when this light comes on. By the way it is referred to as a "Check engine light"

I had the exact same problem. The mechanic found a spark plug that was leaking on the back of the engine that was a pin to get to.
He replaced all plugs and wires and I no longer have this problem, so you may be onto something with the plug wire being loose.
SOURCE: engine stalls, check engine light, not fuel filter.
the white smoke as it stalls could be steam in the exhaust. This is caused by coolant leaking into cylinders from a leaking head gasket. You should check cylinder compression next with a compression tester.
SOURCE: rough idle after warm up
I'd take a look at the temp sender...the engines computer may be
"thinking" the engine is still cold when it's not. That would cause it
run rich (and rough) after it's warmed up. Generally the sender can be
tested with an ordinary volt/ohmeter but you will need the
specifications available in most inexpensive manuals. As with any
complicated electronics system, I can only give you my best guess,
without the luxury of doing any hands-on testing myself.
Good Luck!!

After driving for a while and the engine becomes hot, when you park the car for a while, does this "for a while" mean enough time for the engine to cool down or not?
The reason why this is important is because an engine can stall for a number of reasons, and finding out the conditions of its stalling obviously helps narrow down the cause of the stall.
If it stalls, you say, when the engine cools down after being parked for a while, this handy diagnostic article will help assess the cause of your problem:

If it stalls again, like you said, after warming up and driving for a bit, the ambient temperature may be too as well as the engine itself, which then you should be inclinde to read this diagnostic article:
http://yourhandymanzone.com/Your_Handyman_Zone_How_To_Pages_Vehicle_Car_Zone_Cars_Trucks_Vans_Engine_System_Engine_Stalls_When_Hot.htm
You may very well be right its due to fuel starvation, particularly as to the malfunctioning of the EGR, as noted in the article.
I'm sure these articles will provide you with great insight.
Good luck!

Ok it would be good that you would make a diagnosis in AutoZone make them free, according to what you say may have trouble in the coolant sensor or the MAF sensor but I recommend first a scaner.Thanks
Hello
When the service engine
soon light (Also called the check engine light or engine management
light) is turned on this is to alert you to the fact that Powertrain
Control Module (computer) has detected a failure somewhere in the
systems it controls you may not feel any difference in the way the
engine runs, this can be the transmission or the engine or emission
system, there are fault codes set in the modules memory for these
faults. What needs to happen now is to have the powertrain control
module scanned with a special tool called an OBD2 electronic engine
control scanner or a OBD2 code reader. Once the code(s) are read then
you must perform the diagnostics for each code and make the
appropriate repairs based on the findings of the diagnosis that was
performed, this is called doing "Pinpoint" testing.
