Hello everyone. I have a Fiat croma, diesel, manual, 150 hp, 2007. I changed the EGR, the collector sensor, collector cleaning, particular filter cleaning and it is still blocked. I have put injectors cleaner also. Driving in low gear it simply gets blocked, when i put it in Neutral and go to +3500 rpm it unclogs, then at traffic lights it gets blocked again. Lately it can even move from parking, even when the gas pedal is full presed it would go just a bit over 1000 rpm.The computer does not show any kind of error. Any ideas anyone? Thank you in advance
