Hi,
I have a Marea 1.9 JTD (year 2001) with 110.000km on the clock and it has black smoke coming from the exhaust.
It does not burn any oil, since i've driven it 8000km so far and did not notice any change in oil level since i've changed it.
Water levels OK, too.
Starts OK (no smoke) even when cold.
The thing is, when accelerating, and revs are above 2500, black smoke comes out from the exhaust. If revs are even higher, above 3000, the amount of smoke increases rapidly.
It also spits out a giant cloud of smoke when I accelerate a bit harder (pedal about halfway to the floor), does not matter where the revs are.
And if I push the pedal to the floor, well, you can imagine the amounts of smoke I get..
Some say that it is normal for a diesel to smoke, but my friend has the same Marea 1.9 JTD, altough somewhat older (1999) and I was driving behind him all the time on the 900km distance and could not see any noticeable amount of smoke coming from his exhaust. Also, when climbing a hill i would stay way behind him (same load in both cars). The same on a flat road, but less noticeable.
Also, I've driven a 50HP car before Marea and I expected a significant increase in power from a 110HP car, but it did not happen.
So, there must be something wrong
No error lights on the dashboard.
I've browsed through other posts, and came accross similar problems, with solutions like EGR valve cleaning, or mass air flow sensor, lambda sensor and so on.
What is the difference between air flow sensor and lambda sensor (if any)?
Where is the EGR valve? How to clean it?
Where is the MAF sensor? I've heard that someone recommended that MAF sensor could be boiled in water. Is this true?
Thanks in advance...
