Hi, I am new to the site and need some advice. I have a 2005 Neon SXT that has a lot of engine vibration. I have had ALL of the motor mounts replaced, the timing belt and water pump replaced, the Idler Control valve cleaned, new plugs and wires, and just purchased new tires all the way around.
I feel the engine shake while idling, feel it in the steering wheel and accelerator, the dash, everything! Tire kingdom guy told me that a lot of the neons shake if the coolant motor is broke, and gave me a quote for 535.00 to a new coolant assy. Didn't even "look" at it, just said it was common, REALLY? That's hard for me to believe. I am doing this "process of illimation here" but it is so costly. Does anyone have any ideas?

no such thing as a coolant motor. Might have a bad water pump, but they would not cause a vibration. Check all your motor mounts, one may be bad. top pass side is an easy change the one below it not so much. get a chilton manual and look and the locations for your year and model. If you didnt replace them check and make sure they were changed. May need the intake cleaned or injectors, also double check your timing since the belts were changed, they have to be spot on!
