I have a 2002 Ram 4.7L, and I started to notice that when i start my engine the engine surges to life at a VERY high RPM. Once the engine is running it tends to idle erratically. I have searched everywhere for a vacuum leak and can't find anything. So I'm starting to suspect that it's electrical somewhere regarding a sensor in the intake system. Does anyone know what is causing this problem and/or know how to fix it?
I have a 2002 quad cab with a 287, 4.7 L engine. Would anyone know what years of engines would be compatible with my my truck from a "long block" stand point ?? I'm looking to rebuild one to swap out with mine for a "spare" engine.
