Hello. In my 2002 Neon i have noticed the the car trembles a lot for being a gasoline engine car when it is in idle. If you use any electric stuff like power windows, interior lights or the radiador fans starts, then it trembles even more.
Have you ever noticed this?
I have tested the alternator but i am not familiar with this stuff. Can you see and tell me if the alternator reading is normal? What other thing cam cause this behaviour? I have checked the IAC valve and seems to be in a good shape.

 

I would pull the alternator off and take it to a parts store have them run a test. After watching the video I believe you alternator is about to die.

 

Hello. Look what i have found:

In that thread sone people describe my symtomps, and in the almost last post, one person says that he fixed it in 3 neon cars by replacing the exhaust flex flange.
What do you think about it? Can it be possible?
