Good morning, a Fiat Croma 2400 JTD year 2011 150,000 km with poor engine performance and excessive smoke entered the workshop

replaced the egr valve worked well for a short time but then the condition worsened

the engine did not rev up badly and the exhaust smoke was excessive

we checked the intake manifold and noticed that the rod connecting the butterflies on the manifold had come off completely and was no longer making the butterflies work; we restored everything with a craftsmanship operation without dismantling anything and the car now works fine

Greetings to all

Claudio
