I've been running into some recurring issues with my 2018 ram 2500 6.7cummins's intake system and wanted to get some advice before deciding on my next steps. One of the main problems is frequent carbon build-up in the intake manifold, which seems to be affecting both engine performance and fuel efficiency. Despite regular cleanings, the build-up returns quickly, and I can't seem to find a long-term solution. Another issue is that the airflow through the intake seems restricted, leading to a noticeable drop in power, especially at higher RPMs. I’ve checked for leaks and performed routine maintenance, but the problem persists. Additionally, I keep getting a check engine light related to the EGR system, even after replacing several components. The light eventually comes back, and I'm starting to wonder if the design of the intake manifold or something related to it could be causing these recurring issues. Before I consider making any significant modifications, I wanted to see if anyone else has dealt with similar problems and found an effective solution. Any advice or insight would be much appreciated!
