With 200,000 miles, if you have all golds would look at first of all the egr and inlet manifold which surely are to clean. Normally they are clogged, and then also with a map that is not what I have is very

Egr excluding electrically and is also flanged. Dpf removed with straight pipe then they are not the problem 100%, or at least I think. That's why seeing the symptoms I think it is the mass air flow sensor

You throw it there. If the dpf you out of the sw and not in the hand, it can be that you have some failure that diagnosis you don't see because you have the dtc cleared.

But it is more than a year that I deleted the dpf and before I had these problems now are just to low... the high is good!then when I disconnected the outlet of the mass air flow sensor and the display, I marked the engine failure so I believe the dtc is working. Then with the Edf I found in the historical error and the I have reset. Anyway in short, I replace the valve pierburg depression turbine, and even if it were not evil, not the ago. I prefer to slowly replace all of these components to return to the better performance of the machine

I Errecinque... a nice cleaned up the intake manifold (maybe including the elimination swirl) often does wonders...

But cleaning up the intake manifold with those specific products might be a good solution? The swirl have been locked open.

As for me, I would never use those spray products... I know of someone who has exaggerated and made a nice hole in a piston... if possible always best to remove the manifold and do a good manual cleaning and in-depth

However, there are conflicting opinions. Some have said that they benefited a charity. Obvious that you must not overdo it. In any case, I'd get the one specific to the liqui moly that is a brand name great

You have never removed a manifold is clogged by the sludge of oil vapours recirculation and egr...?
I assure you that one spray is not enough!!!!

I'd like to do it but I've read that is too long and complicated for the fact that you must also act on the distribution.I speak of the alfa 159.
Then, if you have a simple guide and which prevents disassembly of the distribution, we would appreciate it...

Distribution...?????!!!!! I had a 159 jtdm 150cv and I do not know.
