Dirty clogged Diesel engine

[AngryRB]

I have a Saab 9-3 with a 1.9Tid engine, it pulled a check engine light and so i took the EGR gear off and it was fully choked up with carbon/soot.  I am going to block that off and run a DPF additive to the fuel as it currently has very little performance under 2000rpm, at 2000rpm it takes off but its annoying having that lag...

 

Question, if i attach a water methanol kit just before the intake manifold, will that clean the intake manifold, engine and even the exhaust, will it clean the DPF even...and will it give me some low end performance assuming it should pull just off idle...????

The internet is your friend........do some research.  Power output and where you make it depends on the setup.  But it should over time do the cleaning.

I just sold my Saab V6 non turbo. Always liked Saabs and got it cheap but when I got into the Saab forums the list of problems and expensive fixes cured me.

Don't know about the diesels but many petrol engines had inadequate crank case ventilation and aftermarket kits were eventually produced. WMI may well help to clean up your engine but as for performance many of the turbos were small and weak and for example for petrol engines replacement with a TDO4 was often suggested.
