Technical Bravo 1.9Mjet stuttering after EGR replacement

[brecofiat]

Hi,

Please let me know if somebody else had this problem.

Recently my Bravo was loosing power at low power and on light acceleration. I decided to replace the EGR valve and this problem disappeared.

Unfortunetely after the replacement the car started to stutter under acceleration (at 2000-2500 rpm). If I open the windows I can hear a strange rustling noise when the stuttering occurs. It seem like the EGR is opening and closing repeatedly.

Do you have any idea?

Thank you.

You didn't mount the EGR and its seals correctly.

What you hear is exhaust fumes leaking out.

I have the same problem as @brecofiat, I had this before. After check engine light went on, and EGR valve was the error that was blocked. I cleared the error 3-4 times, during that time when EGR was blocked, I did not notice any lose in power in light acceleration from 2000-2500 rpm. Suddenly one day I noticed it again, I connected the phone to ECU, and saw that EGR was again in operation(not blocked). (It unblocked itself). After some days I opened EGR myself, and cleaned it completely. Also I noticed that intake manifold had a lot of oiled dust residue, but EGR itself had dry residue. I think this is another problem I have to watch. Now back to EGR, after I cleaned it, I put it in place. Now I notice from ECU that it opens e closes smoother then before cleaning. BUT time to time I notice the lose of power, I hear the stutter sound like lose of pressure from Turbo and it fills like you breaking in 0.5 second interval. But if you push the acceleration pedal more than that and the EGR goes fully closed, I do not notice any of those things, the acceleration go very smooth.
I do not know what is the fault that does it! I may upload video or photo I capture from phone app, that shows EGR, Pedal %, rpm, power, boost, speed, MAF and Load.
