Hello, all, and Roll Tide. I've got a 2008 SXT that I've had since she was new. I starting getting cat codes, so I went the cheap route and bought some catalytic converter cleaner and used my OBDII tester to reset the codes. The code came back, so I went to Rock Auto and ordered a new cat. I also ordered new oxygen sensors from Advance Auto Parts. The cat wasn't hard at all to replace, all told took about three hours. Since replacement, sometimes when the car has been sitting for a bit, she doesn't want to start. I turn the key and there's a clicking sound--not the battery is almost dead clicking sound, a different one. If I hold the key all the way over, so far eventually she starts. Any suggestions on a fix for this?
