Rough Idle problem, maybe electrical
ok this is what is going on. about a month ago my keyless remote was sending wrong signals to the alarm, most likely a weak battery in the remote, switched the remote have 2, then it locked the engine one morning so I had to call an auto locksmith, he replaced the lead wire and the security system is behaving normal BUT now I seem to have some kind of a drain on the battery causing a rough idle. OK I ran over to sears had them check the battery and alternator, both are fine so that's not what my problem is!I've taken it to several Dealers as well as a repair shop to have them run a complete diagnostic. Always calling ahead and scheduling an appointment for 8am and letting them know I have no means of transportation back and forth so I have to wait for the results and depending on what needs to be done if they can't do it the same day I will bring it back when they have the time & parts to work on her while I wait, which they all tell me is no problem, that a diagnostic will only take a few hours at most. OK so each place I bring her to by 8am they take one look at my mileage (26000)
keep me waiting most of the day, than inform me they haven't had time to run any tests and I have to leave her
that is not going to happen
I'm getting tired of rushing over to be their first when they open and having to leave at the end of the day without even a diagnoses . Any suggestions.

Any suggestions.Took it to a local shop, highly rated, work on high end cars, used before whom I trusted. Brought it by on a friday had a quick look see, said she was to hot to check anything that day and made an appointment for 8am the following Tuesday. 8am on Tuesday they drove me home said they would call as soon as they finished a diagnostic, Called them at 12:30 Nothing, called again at 2:30 than said " Let's do a tune up and then well check to see whats going on, you'll have to leave it a couple of days, Daaaaaaa! They never ran a computer diagnostic as they said they could, they never checked anything not a speck of dust was moved from under the hood. Yes I said dust, a lot of dust from construction at my condo and told them to check all the filters as well,picked her up at 3, another wasted day and no result.

If you can't do the work yourself keep looking around until you find a GOOD shop they are out there, ask around...

Been doing that, but did want to up date you and all who have been so kind to respond. I took it to another dealer this morning 8am
and finally this one didn't play games and took her right in to run the diagnostic, they even let me periodically stick my nose in to see what they were doing
. Battery & alternator fine, But he thinks it still might be an intermittent problem with the alternator not running smoothly based on the volt fluctuation and vibrations at idle. Put new rings in the gasket which it did need, and did a fuel injector clean out, said gas in tank was clean but there was a little carbon buildup on the plugs but didn't need to be changed, that was fine so I didn't need a tune up after all and changed filters. Well at least I know there is nothing major going on but it's still vibrating at stopping. Guess I'll run her a bit and see if it quiets down after the fluids have a chance to run thru her. He told me to keep the volt meter on and keep an eye on her, she seem to be running between 13.6-14 but slow speeds (0-29) jumping from 14- 13.2, said if it drops to 12 at any time to call and bring her back and he'll check the alternator again. This tech seemed to really know what he was doing, explained everything step by step of what he was doingWell, I'll keep you all up today as I know more. Thanks again for all your imput's.
Well 2 year's later and multi mechanics and finally found the problem
A 1k remedy just hope it's not another "let's try this and see".
Good luck.
