Hello, I have a 2008 Charger with the 2.7L engine with 141k miles on it. I just replaced the timing chain, oil pump, water pump, map sensor, intake charge temp sensor, new cardone throttle body, radiator and thermostat, and all the seals to the injectors as well as the intake manifold to include the small egr seal and added a little extra rtv to ensure that little guy sealed properly. My problem is when it first started it idled rough and was in limp mode with the check engine and throttle body lightning bolt flashing. I’ve attempted the procedures attached below as well as the fuse pull for the ecu and connecting the two battery terminals overnight to drain the ecu power in an attempt to force the ecu to reset. Now it won’t even start but for a second up to about 500rpm then dies. The engine is only throwing the throttle body code with both the old and new throttle bodies installed. I’m sure it’s something simple I’ve overlooked but can anyone steer me in the right direction?
