I've just had my 2014 1500 R/T with JBA LTs installed and dynotuned. Now when I first start my engine, before warm up the engine and truck will shake and run up to about 2000 RPM then mellow down and is normal. If I start the engine at running temp all is well. Is it the 02 sensors warming up, the MDS struggling, or who knows? I had an exhaust leak with loud tick and replaced exhaust gasket, but did get some carbon build up in throttle body, not sure if its related to my issue.
