Car Stuttering While The Radio Is On?!!

[djfergi]

I noticed lately that my car stutters while in drive when my radio is on. If I shut the radio off, my car idles smooth. I just replaced my battery about a month ago. Does anyone have this happen to them or know what would cause this?

You must be pulling some deep bass notes on the radio for that.

I have not heard of that symptom. I would think it might be coils though.

LOL!! Sorry I should have explained a little better. I notice the stuttering while the radio is on. The car almost feels like it's going to stall. I was coming home from school tonight. I was at a stop light. The car dropped down to 500 RPM then shot right back up to 700RPM then dropped again to five hundred. This all happened why I was waiting at the light. I replaced the battery about a month ago. If my idle was never set correctly, could this cause the car to stutter like it does?

I agree that I would check plugs and coils, as a first thing. Though I also admit that the connection to the radio confuses me (pun intended ).

The V8 learns it's idle really quick with out any user intervention.

An idle speed that is moving up and down is usally the IAC as it is the only thing that is meant to control the idle. May be a vacuum leak though.

Well I fixed my SHO. I just reset the idle and the car is running perfect. Thanks fellas for all the help.
