My car runs just fine when i'm at a redlight waiting, in front of the house waiting, driving locally, driving on the highway... However, when i'm stuck in traffic for say a good 25-30mins or so, my car starts to shake. It will shake when the car is not in motion during the traffic. When I say "stuck in traffic" I mean that i'm at a complete stop then after 45secs or so I get to roll 2 car lengths or so. Now, other from the traffic the car runs completely fine, what could be causing this?

Thanks

Watch your tachometer. Does it dip below normal idle at all?

 

I haven't been stuck in traffic in awhile, so I haven't had a chance to check that out recently. But if memory serves me right, the rpms did not drop below idle and throwing the gear into neutral didn't help it either. (Automatic Transmission)

 

Maybe you should take another route with less traffic????????

 

Could be motor mounts. Got a CEL?

 

i have a similar problem with the car shaking.. it really pisses me off too... i dont have any mil codes or anything... what i would say is check ur IACV and your motor mounts cuz i have dont everything and they are my last resort..
