Excessive vibrations when lights and a/c on

[fivese7en]

Hey guys,

My car is vibrating a lot when I start the engine and after 10 minutes turn lights or a/c on and stop at a traffic light - is it normal?

I got my alternator fixed 3 months ago by dealers mechanic because one of the diodes blew.

Absolutely not normal mate. Should be smooth-as. You said it vibrate after you started the engine, so it could be fuel related (eg fuel injection).

More like after I turn on different features like a/c after I start the engine - but it only happens when I stop somewhere or at a traffic light

You can isolate the a/c but just turning on the fan, if it still chuckles with fan only then something electrical.

Its fan, a/c lights etc. anything electrical - I thought it might be the alternator?

I got service in January so might as well get it check out then. Any good mechanic's in the area aem?
