I have had the car for 2 days now and I have a couple general questions and 1 problem so far. (2005 SRT-6 Coupe)

1. Today while driving the car all gauges quit working, odometer, clock and all warning lights came on, car ran fine and the radio was still on so it couldn't have been a complete power loss. It only stayed like that for about 3 seconds then everything came back on and worked like normal the rest of the 10 miles to my house. I did try a search but nothing that seemed to match my problem popped up.

2. How would I determine if the car already has an aftermarket pulley? I don't know if there is any certain difference or certain markings I could look for. Reason I ask is I can't find any info about this car on the forum and there are a lot of performance parts on the car from Needswings.

3. Is it normal for the car to ride so rough? I do not believe it is lowered, but it seems real rough, I also haven't owned a car with low pro's in years, maybe that's the problem.

Any info would be greatly appreciated, thanks
