2006 Dodge Ram 1500 Q&A
2006 Dodge Ram 1500 Question: 4.7 engine with 60k miles is starting to idle very rough.
Need to check to see if the engine is using any coolant, I have seen a lot of 4.7 rough idle/misfire codes being caused by a leaking head gasket, so be sure to check that the coolant is not being used up. Other wise, you need to check the plugs, coils etc to see if the misfire/poor idle is ignition related. Not sure which A/C fan you mean, the electric fan on the radiator or the blower motor in the dash, but either way, if they are getting noisy, it is most likely a bit involved than a set screw. - dandd
