Hello everyone. I'm a complete newbie when it comes to car audio installs, but wanted to give it a go. Last night, I installed a new Pioneed deck in my 2003 Lancer Rally. The install itself seemed to go splendidly, though I did notice when driving the car this morning that it idles a bit rough.

I grounded the deck but am thinking perhaps that's my issue? Any and all advice appreicated...

Thanks,
R

 

After messing with cars and stereos for 16 years I HIGHLY doubt anything you did could cause your idle to be screwy,,,maybe give it a day..or 6
