Eureka!!!! Your problems are solved.. If your having shuttering problems, problems with your EGR, idle air control, throttle positioning sensor, car not turning over, car acting erratically or dying out and even transmission issues such as going in limp mode not switching gears... It is in 2 places the wire harness!!!!
1) Under the tire well above the dog bone for suspension is a Negative or ground cable bolted to the transmission this sometimes comes loose and will prevent your car from starting or even turning over.. There is also a harness that passes over this bolt which will rub out on the back side in time.. This will cause problems in the egr, i.a.c., t.p.s and Ats.... Fix the wire fix the problem
2) if you open your hood under your battery not directly but down low youll see your solenoid packs and other transmission sensors follow these to the thicker wire harness down to wear it almost touches the frame and meets other wire harnesses... The back side of this "crossroad" rubs up against some kind of flange on the transmission with bolt holes in it.. This is the problem with transmission issues in the 2004 Chrysler Pacifica 3.5l.. Fix the wire fix the problem!!! I spent alot of money on parts to figure out this simple easy cheap fix.. Make sure to reinforce protection in the back of theose wires during fix.. Hope i save dyou some time and money

 

just curious, would this also cause "check engine" light to come on?
