Ls2 rough start up
I replaced my throttle body on my LS2 with another stock throttle body and the car ran fine. I then had to adjust my insurance which required pictures and filling out forms and the car has been parked for about a month. It needs a new battery, but I can charge the battery and then start the car. Now when the car is started it will idle rough and backfire a number of times and then after a few minutes it will smooth out and run normal. The car is not throwing any codes and I can not drive the car until all the insurance stuff is finalized. Any ideas? Thanks
