Blew an exhaust valve on 11/26/13, had both valves replaced and 4 new OEM stock injectors installed - engine ran like a champ until recently.

0˚ TDC, full 160 PSI in all cylinders

New head installed in May 2013

Had a minor FRT DRVR side collision two weeks ago, frame was missed and nothing effected the engine - radiator support was damaged, along with LFT CV axle and what you see.

After mending her at the body shoppe, only after 5 mins of driving, codes started up again.

OEM Coil pack and wires replaced - 8/2012

OEM Spark plugs - 11/26/2013

OEM O2 sensors - Summer 2011

ATi damper installed - Summer 2011

Car is idles rough immediately after start-up, and becomes worse when braking??

Please help me.
