Missing

Car missfires at idle. Hooked up my buddys scan tool just to see and when the car is at idle it will see as many as 12 missfires on two cylinders, and a couple in all of the other cylinders as well in each cycle. Drive down the road and all show 0 until i let off the gas and it is coasting. Any help as to where to start would be appreciated.

List your modifications. If it has a cam and the misfires aren't tuned out this is normal.

Is your car tuned for the cam?

i had one tune and the converter worked fine locked like it was supose to and no missfires. Then i went to another shop to have the tune done over and everything was fine until i left the shop and 10min down the road the converter started acting up unlocking while in OD and it hasn't been the same since. Mainly i just wanted to make sure that it was ok to drive until i get a chance to take it back. The place where i got it tuned is 2hrs away and i dont have time to take it back till next month.
