Hello
For some time my defender puma lacks power I cleaned the maf sensor and the map sensor. I made a test with the maf sensor unplugged it doesn't change anything, then I reconnected the maf sensor.
hen I made a test in neutral to go up in mode to the maximum given whatever throttle of the accelerator, I have slightly black smoke coming out but it is barely visible.

by doing the test of maximum speed idle in neutral I have a kind of whistling sound when I decelerate


thank you for answer

I live in France so I use google translate

Have you checked or changed your intercooler hoses?
Common problem with the 2.2 and most people change them to Silicone.
These may have a small hole in and generally casue a Whooshing noise.

I changed the sensor maf I bought the brand ntk (ngk). I have a slight improvement in performance. I then operated the variable geometry by hand no hard point I had to add penetrating oil.




I did the test by unplugging the egr valve and did a little test drive, it looked like it worked a little better.

Some time ago my egr valve made a weird noise when the engine was stopped, like it was spinning in a vacuum. I c is who there is the self cleaning stops for me its done 3 times chunk and clunk at the end. Wouldn't my egr valve have a defect like it remains slightly open ?

I changed the turbo hoses made a road test and it didn't change anything just a little because I had taken silicone hoses
should i do a computer reset as i changed my maf sensor?
